WITNESSETH:

WHEREAS, for its lawful
corporate purposes, the Company has duly authorized the issuance of its Floating Rate Junior Subordinated Deferrable Interest Debentures due 2033 (the Debentures) under this Indenture to provide, among other things, for the
execution and authentication, delivery and administration thereof, and the Company has duly authorized the execution of this Indenture; and

WHEREAS, all acts and things necessary to make this Indenture a valid agreement according to its terms, have been done and performed;

NOW, THEREFORE, This Indenture Witnesseth:

context otherwise requires) for all purposes of this Indenture and of any indenture supplemental hereto shall have the respective meanings specified in this Section 1.1. All accounting terms used herein and not expressly defined shall have the
meanings assigned to such terms in accordance with generally accepted accounting principles and the term generally accepted accounting principles means such accounting principles as are generally accepted in the United States at the time
of any computation. The words herein, hereof and hereunder and other words of similar import refer to this Indenture as a whole and not to any particular Article, Section or other subdivision.

Additional Interest has the meaning set forth in Section 2.11.

Additional Junior Indebtedness means, without duplication and other than the Debentures, any indebtedness, liabilities or obligations
of the Company, or any Subsidiary of the Company, under debt securities (or guarantees in respect of debt securities) initially issued after the date of this Indenture to any trust, or a trustee of a trust, partnership or other entity affiliated
with the Company that is, directly or indirectly, a finance subsidiary (as such term is defined in Rule 3a-5 under the Investment Company Act of 1940) or other financing vehicle of the Company or any Subsidiary of the Company in connection with the
issuance by that entity of preferred securities or other securities that are eligible to qualify for Tier 1 capital treatment (or its then equivalent) for purposes of the capital adequacy guidelines of the Federal Reserve, as then in effect and
applicable to the Company (or, if the Company is not a bank holding company, such guidelines applied to the Company as if the Company were subject to such guidelines);



---

provided,however, that the inability of the Company to treat all or any portion of the Additional Junior Indebtedness as Tier 1 capital shall
not disqualify it as Additional Junior Indebtedness if such inability results from the Company having cumulative preferred stock, minority interests in consolidated subsidiaries, or any other class of security or interest which the Federal Reserve
now or may hereafter accord Tier 1 capital treatment (including the Debentures) in excess of the amount which may qualify for treatment as Tier 1 capital under applicable capital adequacy guidelines.

Connecticut are permitted or required by any applicable law to close.

Capital Securities means undivided beneficial
interests in the assets of the Trust which rank pari passu with Common Securities issued by the Trust; provided,however, that upon the occurrence and continuance of an Event of Default (as defined in the Declaration), the

guarantee trustee, or other Persons that operates directly or indirectly for the benefit of holders of Capital Securities of the Trust.

Capital Treatment Event means the receipt by the Company and the Trust of an opinion of counsel experienced in such matters to the effect that, as a result of the occurrence of any amendment to or change (including any
announced prospective change) in, the laws, rules or regulations of the United States or any political subdivision thereof or therein, or as the result of any official or administrative pronouncement or action or decision interpreting or applying
such laws, rules or regulations, which amendment or change is effective or which pronouncement, action or decision is announced on or after the date of original issuance of the Debentures, there

is more than an insubstantial risk that the Company will not, within 90 days of the date of such opinion, be entitled to treat an amount equal to the
aggregate liquidation amount of the Capital Securities as Tier 1 Capital (or its then equivalent) for purposes of the capital adequacy guidelines of the Federal Reserve, as then in effect and applicable to the Company (or if the Company
is not a bank holding company, such guidelines applied to the Company as if the Company were subject to such guidelines); provided, however, that the inability of the Company to treat all or any portion of the liquidation amount of the
Capital Securities as Tier 1 Capital shall not constitute the basis for a Capital Treatment Event, if such inability results from the Company having cumulative preferred stock, minority interests in consolidated subsidiaries, or any other class of
security or interest which the Federal Reserve or OTS, as applicable, may now or hereafter accord Tier 1 Capital treatment in excess of the amount which may now or hereafter qualify for treatment as Tier 1 Capital under applicable capital adequacy
guidelines; provided further, however, that the distribution of Debentures in connection with the liquidation of the Trust shall not in and of itself constitute a Capital Treatment Event unless such liquidation shall have occurred in
connection with a Tax Event or an Investment Company Event.

principal executive officer, the principal financial officer or the principal accounting officer of the Company.

substantially in the form of Exhibit A attached hereto. The Debentures shall be in registered, certificated form without coupons and in minimum denominations of $100,000.00 and any multiple of $1,000.00 in excess thereof. Any attempted transfer of
the Debentures in a block having an aggregate principal amount of less than $100,000.00 shall be deemed to be void and of no legal effect whatsoever. Any such purported transferee shall be deemed not to be a holder of such Debentures for any
purpose, including, but not limited to the receipt of payments on such Debentures, and such purported transferee shall be deemed to have no interest whatsoever in such Debentures. The Debentures shall be numbered, lettered, or otherwise
distinguished in such manner or in accordance with such plans as the officers executing the same may determine with the approval of the Trustee as evidenced by the execution and authentication thereof.

Section 2.4. Execution of Debentures. The Debentures shall be signed in the name and on behalf of the Company by the manual or
facsimile signature of its Chairman of the Board of Directors, Chief Executive Officer, Vice Chairman, President, one of its Managing Directors or one of its Executive Vice Presidents, Senior Vice Presidents or Vice Presidents. Only such Debentures
as shall bear thereon a certificate of authentication substantially in the form herein before recited, executed by the Trustee or the Authenticating Agent by the manual signature of an authorized signer, shall be entitled to the benefits of this
Indenture or be valid or obligatory for any purpose. Such certificate by the Trustee or the Authenticating Agent upon any Debenture executed by the Company shall be conclusive evidence that the Debenture so authenticated has been duly authenticated
and delivered hereunder and that the holder is entitled to the benefits of this Indenture.

In case any officer of the Company who shall
have signed any of the Debentures shall cease to be such officer before the Debentures so signed shall have been authenticated and delivered by the Trustee or the Authenticating Agent, or disposed of by the Company, such Debentures nevertheless may
be authenticated and delivered or disposed of as though the Person who signed such Debentures had not ceased to be such officer of the Company; and any Debenture may be signed on behalf of the Company by such Persons as, at the actual date of the
execution of such Debenture, shall be the proper officers of the Company, although at the date of the execution of this Indenture any such person was not such an officer.

Every Debenture shall be dated the date of its authentication.

Section 2.5. Exchange and
Registration of Transfer of Debentures. The Company shall cause to be kept, at the office or agency maintained for the purpose of registration of transfer and for exchange as provided in Section 3.2, a register (the
Debenture



9



---

Register) for the Debentures issued hereunder in which, subject to such reasonable regulations as it may prescribe, the Company shall provide
for the registration and transfer of all Debentures as in this Article II provided. The Debenture Register shall be in written form or in any other form capable of being converted into written form within a reasonable time.

Debentures to be exchanged may be surrendered at the Principal Office of the Trustee or at any office or agency to be maintained by the Company for such
purpose as provided in Section 3.2, and the Company shall execute, the Company or the Trustee shall register and the Trustee or the Authenticating Agent shall authenticate and make available for delivery in exchange therefor the Debenture or
Debentures which the Securityholder making the exchange shall be entitled to receive. Upon due presentment for registration of transfer of any Debenture at the Principal Office of the Trustee or at and office or agency of the Company maintained for
such purpose as provided in Section 3.2, the Company shall execute, the Company or the Trustee shall register and the Trustee or the Authenticating Agent shall authenticate and make available for delivery in the name of the transferee or
transferees a new Debenture for a like aggregate principal amount. Registration or registration of transfer of any Debenture by the Trustee or by any agent of the Company appointed pursuant to Section 3.2, and delivery of such Debenture, shall
be deemed to complete the registration or registration of transfer of such Debenture.

All Debentures presented for registration of
transfer or for exchange or payment shall (if so required by the Company or the Trustee or the Authenticating Agent) be duly endorsed by, or be accompanied by a written instrument or instruments of transfer in form satisfactory to the Company and
the Trustee or the Authenticating Agent duly executed by the holder or his attorney duly authorized in writing.

No service charge shall be
made for any exchange or registration of transfer of Debentures, but the Company or the Trustee may require payment of a sum sufficient to cover any tax, fee or the governmental charge that may be imposed in connection therewith.

The Company or the Trustee shall not be required to exchange or register a transfer of any Debenture for a period of 15 days next preceding the date of
selection of Debentures for redemption.

Notwithstanding anything herein to the contrary, Debentures may not be transferred except in
compliance with the restricted securities legend set forth below, unless otherwise determined by the Company, upon the advice of counsel expert in securities law, in accordance with applicable law:

AMOUNT OF LESS THAN $100,000.00 SHALL BE DEEMED TO BE VOID AND OF NO LEGAL EFFECT WHATSOEVER.

THE HOLDER OF THIS SECURITY AGREES THAT IT
WILL COMPLY WITH THE FOREGOING RESTRICTIONS.

Section 2.6. Mutilated, Destroyed, Lost or Stolen Debentures. In case any
Debenture shall become mutilated or be destroyed, lost or stolen, the Company shall execute, and upon its written request the Trustee shall authenticate and deliver, a new Debenture bearing a number not contemporaneously outstanding, in exchange and
substitution for the mutilated Debenture, or in lieu of and in substitution for the Debenture so destroyed, lost or stolen. In every case the applicant for a substituted Debenture shall furnish to the Company and the Trustee such security or
indemnity as may be required by them to save each of them harmless, and, in every case of destruction, loss or theft, the applicant shall also furnish to the Company and the Trustee evidence to their satisfaction of the destruction, loss or theft of
such Debenture and of the ownership thereof.

The Trustee may authenticate any such substituted Debenture and deliver the same upon the
written request or authorization of any officer of the Company. Upon the issuance of any substituted Debenture, the Company may require the payment of a sum sufficient to cover any tax or other governmental charge that may be imposed in relation
thereto and any other expenses connected therewith. In case any Debenture which has matured or is about to mature or has been called for redemption in full shall become mutilated or be destroyed, lost or stolen, the Company may, instead of issuing a
substitute Debenture, pay or authorize the payment of the same (without surrender thereof except in the case of mutilated Debenture) if the applicant for such payment shall furnish to the Company and the Trustee such security or indemnity as may be
required by them to save each of them harmless and, in case of destruction, loss or theft, evidence satisfactory to the Company and to the Trustee of the destruction, loss or theft of such Debenture and of the ownership thereof.

Every substituted Debenture issued pursuant to the provisions of this Section 2.6 by virtue of the fact that any such Debenture is destroyed, lost
or stolen shall constitute an additional contractual obligation of the Company, whether or not the destroyed, lost or stolen Debenture shall be found at any time, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Debentures duly issued hereunder. All Debentures shall be held and owned upon the express condition that, to the extent permitted by applicable law, the foregoing provisions are exclusive with respect to the
replacement or payment of mutilated, destroyed, lost or stolen Debentures and shall preclude any and all other rights or remedies notwithstanding any law or statute existing or hereafter enacted to the contrary with respect to the replacement or
payment of negotiable instruments or other securities without their surrender.

Section 2.7. Temporary Debentures. Pending the preparation of definitive Debentures,
the Company may execute and the Trustee shall authenticate and make available for delivery temporary Debentures that are typed, printed or lithographed. Temporary Debentures shall be issuable in any authorized denomination, and substantially in the
form of the definitive Debentures in lieu of which they are issued but with such omissions, insertions and variations as may be appropriate for temporary Debentures, all as may be determined by the Company. Every such temporary Debenture shall be
executed by the Company and be authenticated by the Trustee upon the same conditions and in substantially the same manner, and with the same effect, as the definitive Debentures. Without unreasonable delay the Company will execute and deliver to the
Trustee or the Authenticating Agent definitive Debentures and thereupon any or all temporary Debentures may be surrendered in exchange therefor, at the principal corporate trust office of the Trustee or at any office or agency maintained by the
Company for such purpose as provided in Section 3.2, and the Trustee or the Authenticating Agent shall authenticate and make available for delivery in exchange for such temporary Debentures a like aggregate principal amount of such definitive
Debentures. Such exchange shall be made by the Company at its own expense and without any charge therefor except that in case of any such exchange involving a registration of transfer the Company may require payment of a sum sufficient to cover any
tax, fee or other governmental charge that may be imposed in relation thereto. Until so exchanged, the temporary Debentures shall in all respects be entitled to the same benefits under this Indenture as definitive Debentures authenticated and
delivered hereunder.

Section 2.8. Payment of Interest and Additional Interest. Interest at the Interest Rate and any
Additional Interest on any Debenture that is payable, and is punctually paid or duly provided for, on any Interest Payment Date for Debentures shall be paid to the Person in whose name said Debenture (or one or more Predecessor Securities) is
registered at the close of business on the regular record date for such interest installment except that interest and any Additional Interest payable on the Maturity Date shall be paid to the Person to whom principal is paid.

Each Debenture shall bear interest for the period beginning on (and including) the date of original issuance and ending on (but excluding)
September 26, 2003 at a rate per annum of 4.16%, and shall bear interest for each successive period beginning on (and including) September 26, 2003, and each succeeding Interest Payment Date, and ending on (but excluding) the next
succeeding Interest Payment Date (each, a Distribution Period) at a rate per annum equal to the 3-Month LIBOR, determined as described in Section 2.10, plus 3.10% (the Coupon Rate); provided,
however, that prior to June 26, 2008, the Coupon Rate shall not exceed 11.75%, applied to the principal amount thereof, until the principal thereof becomes due and payable, and on any overdue principal and to the extent that payment of
such interest is enforceable under applicable law (without duplication) on any overdue installment of interest (including Additional Interest) at the Interest Rate in effect for each applicable period compounded quarterly. Interest shall be payable
(subject to any relevant Extension Period) quarterly in arrears on each Interest Payment Date with the first installment of interest to be paid on September 26, 2003.



13



---

Any interest on any Debenture, including Additional Interest, that is payable, but is not punctually paid
or duly provided for, on any Interest Payment Date (herein called Defaulted Interest) shall forthwith cease to be payable to the registered holder on the relevant regular record date by virtue of having been such holder; and such
Defaulted Interest shall be paid by the Company to the Persons in whose names such Debentures (or their respective Predecessor Securities) are registered at the close of business on a special record date for the payment of such Defaulted Interest,
which shall be fixed in the following manner: the Company shall notify the Trustee in writing at least 25 days prior to the date of the proposed payment of the amount of Defaulted Interest proposed to be paid on each such Debenture and the date of
the proposed payment, and at the same time the Company shall deposit with the Trustee an amount of money equal to the aggregate amount proposed to be paid in respect of such Defaulted Interest or shall make arrangements satisfactory to the Trustee
for such deposit prior to the date of the proposed payment, such money when deposited to be held in trust for the benefit of the Persons entitled to such Defaulted Interest as in this clause provided. Thereupon the Trustee shall fix a special record
date for the payment of such Defaulted Interest which shall not be more than 15 nor less than 10 days prior to the date of the proposed payment and not less than 10 days after the receipt by the Trustee of the notice of the proposed payment. The
Trustee shall promptly notify the Company of such special record date and, in the name and at the expense of the Company, shall cause notice of the proposed payment of such Defaulted Interest and the special record date therefor to be mailed, first
class postage prepaid, to each Securityholder at its address as it appears in the Debenture Register, not less than 10 days prior to such special record date. Notice of the proposed payment of such Defaulted Interest and the special record date
therefor having been mailed as aforesaid, such Defaulted Interest shall be paid to the Persons in whose names such Debentures (or their respective Predecessor Securities) are registered on such special record date and shall be no longer payable.

The Company may make payment of any Defaulted Interest on any Debentures in any other lawful manner after notice given by the Company to
the Trustee of the proposed payment method; provided, however, the Trustee in its sole discretion deems such payment method to be practical.

Any interest (including Additional Interest) scheduled to become payable on an Interest Payment Date occurring during an Extension Period shall not be Defaulted Interest and shall be payable on such other date as may
be specified in the terms of such Debentures.

The term regular record date as used in this Section shall mean the close of
business on the 15th calendar day next preceding the applicable Interest Payment Date.

Subject to the foregoing provisions of this
Section, each Debenture delivered under this Indenture upon registration of transfer of or in exchange for or in lieu of any other Debenture shall carry the rights to interest accrued and unpaid, and to accrue, that were carried by such other
Debenture.

Section 2.9. Cancellation of Debentures Paid, etc. All Debentures surrendered for the purpose of payment,
redemption, exchange or registration of transfer, shall, if surrendered to the Company or any paying agent, be surrendered to the Trustee and promptly canceled by it, or, if surrendered to the Trustee or any Authenticating Agent, shall be promptly
canceled by it, and



14



---

no Debentures shall be issued in lieu thereof except as expressly permitted by any of the provisions of this Indenture. All Debentures canceled by any
Authenticating Agent shall be delivered to the Trustee. The Trustee shall destroy all canceled Debentures unless the Company otherwise directs the Trustee in writing. If the Company shall acquire any of the Debentures, however, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness represented by such Debentures unless and until the same are surrendered to the Trustee for cancellation.

Section 2.10. Computation of Interest. The amount of interest payable for the Distribution Period commencing on September 26,
2003 and each succeeding Distribution Period will be calculated by applying the Interest Rate to the principal amount outstanding at the commencement of the Distribution Period and multiplying each such amount by the actual number of days in the
Distribution Period concerned divided by 360. In the event that any date on which interest is payable on the Debentures is not a Business Day, then payment of interest payable on such date shall be made on the next succeeding day which is a Business
Day (and without any interest or other payment in respect of any such delay) except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in each case with the same
force and effect as if made on the date such payment was originally payable. All percentages resulting from any calculations on the Debentures will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five
one-millionths of a percentage point rounded upward (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655), and all dollar amounts used in or resulting from such calculation will be rounded to the nearest cent (with one-half cent
being rounded upward)).

(a) 3-Month LIBOR means the London interbank offered interest rate for three-month, U.S. dollar
deposits determined by the Trustee in the following order of priority:

(1) the rate (expressed as a percentage per annum)
for U.S. dollar deposits having a three-month maturity that appears on Telerate Page 3750 as of 11:00 a.m. (London time) on the related Determination Date (as defined below). Telerate Page 3750 means the display designated as Page
3750 on the Dow Jones Telerate Service or such other page as may replace Page 3750 on that service or such other service or services as may be nominated by the British Bankers Association as the information vendor for the purpose of
displaying London interbank offered rates for U.S. dollar deposits;

(2) if such rate cannot be identified on the related
Determination Date, the Trustee will request the principal London offices of four leading banks in the London interbank market to provide such banks offered quotations (expressed as percentages per annum) to prime banks in the London interbank
market for U.S. dollar deposits having a three-month maturity as of 11:00 a.m. (London time) on such Determination Date. If at least two quotations are provided, 3-Month LIBOR will be the arithmetic mean of such quotations;

(3) if fewer than two such quotations are provided as requested in clause (2) above, the Trustee will request four major New York
City banks to provide such banks offered quotations (expressed as percentages per annum) to leading European banks for loans in U.S. dollars as of 11:00 a.m. (London time) on such Determination Date. If at least two such quotations are
provided, 3-Month LIBOR will be the arithmetic mean of such quotations; and



15



---

(4) if fewer than two such quotations are provided as requested in clause (3) above,
3-Month LIBOR will be a 3-Month LIBOR determined with respect to the Distribution Period immediately preceding such current Distribution Period.

If the rate for U.S. dollar deposits having a three-month maturity that initially appears on Telerate Page 3750 as of 11:00 a.m. (London time) on the related Determination Date is superseded on the Telerate Page 3750 by a corrected rate by
12:00 noon (London time) on such Determination Date, then the corrected rate as so substituted on the applicable page will be the applicable 3-Month LIBOR for such Determination Date.

(b) The Interest Rate for any Distribution Period will at no time be higher than the maximum rate then permitted by New York law as the same may be
modified by United States law.

(c) Determination Date means the date that is two London Banking Days (i.e., a business
day in which dealings in deposits in U.S. dollars are transacted in the London interbank market) preceding the particular Distribution Period for which a Coupon Rate is being determined.

(d) The Trustee shall notify the Company, the Institutional Trustee and any securities exchange or interdealer quotation system on which the Capital
Securities are listed, of the Coupon Rate and the Determination Date for each Distribution Period, in each case as soon as practicable after the determination thereof but in no event later than the thirtieth (30th) day of the relevant
Distribution Period. Failure to notify the Company, the Institutional Trustee or any securities exchange or interdealer quotation system, or any defect in said notice, shall not affect the obligation of the Company to make payment on the Debentures
at the applicable Coupon Rate. Any error in the calculation of the Coupon Rate by the Trustee may be corrected at any time by notice delivered as above provided. Upon the request of a holder of a Debenture, the Trustee shall provide the Coupon Rate
then in effect and, determined, the Coupon Rate for the next Distribution Period.

(e) Subject to the corrective rights set forth above,
all certificates, communications, opinions, determinations, calculations, quotations and decisions given, expressed, made or obtained for the purposes of the provisions relating to the payment and calculation of interest on the Debentures and
distributions on the Capital Securities by the Trustee or the Institutional Trustee will (in the absence of willful default, bad faith and manifest error) be final, conclusive and binding on the Trust, the Company and all of the holders of the
Debentures and the Capital Securities, and no liability shall (in the absence of willful default, bad faith or manifest error) attach to the Trustee or the Institutional Trustee in connection with the exercise or non-exercise by either of them or
their respective powers, duties and discretion.

Section 2.11. Extension of Interest Payment Period. So long as no Event of Default has
occurred and is continuing, the Company shall have the right, from time to time, and without causing an Event of Default, to defer payments of interest on the Debentures by extending the interest payment period on the Debentures at any time and from
time to time during the term of the Debentures, for up to 20 consecutive quarterly periods (each such extended interest payment period, an Extension Period), during which Extension Period no interest (including Additional
Interest) shall be due and payable (except any Additional Sums that may be due and payable). No Extension Period may end on a date other than an Interest Payment Date. During an Extension Period, interest will continue to accrue on the Debentures,
and interest on such accrued interest will accrue at an annual rate equal to the Interest Rate in effect for such Extension Period, compounded quarterly from the date such interest would have been payable were it not for the Extension Period, to the
extent permitted by law (such interest referred to herein as Additional Interest). At the end of any such Extension Period the Company shall pay all interest then accrued and unpaid on the Debentures (together with Additional
Interest thereon); provided, however, that no Extension Period may extend beyond the Maturity Date; provided further, however, that during any such Extension Period, the Company shall not and shall not permit any
Affiliate to (i) declare or pay any dividends or distributions on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any of the Companys or such Affiliates capital stock (other than payments of dividends
or distributions to the Company) or make any guarantee payments with respect to the foregoing or (ii) make any payment of principal of or interest or premium, if any, on or repay, repurchase or redeem any debt securities of the Company or any
Affiliate that rank pari passu in all respects with or junior in interest to the Debentures (other than, with respect to clauses (i) or (ii) above, (a) repurchases, redemptions or other acquisitions of shares of capital stock
of the Company in connection with any employment contract, benefit plan or other similar arrangement with or for the benefit of one or more employees, officers, directors or consultants, in connection with a dividend reinvestment or stockholder
stock purchase plan or in connection with the issuance of capital stock of the Company (or securities convertible into or exercisable for such capital stock) as consideration in an acquisition transaction entered into prior to the applicable
Extension Period, (b) as a result of any exchange or conversion of and class or series of the Companys capital stock (or any capital stock of a subsidiary of the Company) for any class or series of the Companys capital stock or of
any class or series of the Companys indebtedness for any class or series of the Companys capital stock, (c) the purchase of fractional interests in shares of the Companys capital stock pursuant to the conversion or exchange
provisions of such capital stock or the security being converted or exchanged, (d) any declaration of a dividend in connection with any stockholders rights plan, or the issuance of rights, stock or other property under any
stockholders right plan, or the redemption or repurchase of rights pursuant thereto, (e) any dividend in the form of stock warrants, options or other rights where the dividend stock or the stock issuable upon exercise of such warrants,
options or other rights is the same stock as that on which the dividend is being paid or ranks pari passu with or junior to such stock and any cash payments in lieu of fractional shares issued it connection therewith, or (f) payments
under the Capital Securities Guarantee). Prior to the termination of any Extension Period, the Company may further extend such period, provided that such period together with all such previous and further consecutive extensions thereof shall
not exceed 20 consecutive quarterly periods, or extend beyond the Maturity Date. Upon the termination of any Extension Period and upon the payment of all accrued and unpaid interest and Additional Interest, the Company may commence a new Extension
Period, subject to



17



---

the foregoing requirements. No interest or Additional Interest shall be due and payable during an Extension Period, except at the end thereof, but each
installment of interest that would otherwise have been due and payable during such Extension Period shall bear Additional Interest to the extent permitted by applicable law. The Company must give the Trustee notice of its election to begin or extend
an Extension Period at least 5 Business Days prior to the regular record date (as such term is used in Section 2.8) immediately preceding the Interest Payment Date with respect to which interest on the Debentures would have been payable except
for the election to begin or extend such Extension Period. The Trustee shall give notice of the Companys election to begin a new Extension Period to the Securityholders.

Section 2.12. CUSIP Numbers. The Company in issuing the Debentures may use CUSIP numbers (if then generally in use), and,
if so, the Trustee shall use CUSIP numbers in notices of redemption as a convenience to Securityholders; provided,however, that any such notice may state that no representation is made as to the correctness of such numbers either as
printed on the Debentures or as contained in any notice of a redemption and that reliance may be placed only on the other identification numbers printed on the Debentures, and any such redemption shall not be affected by any defect in or omission of
such numbers. The Company will promptly notify the Trustee in writing of any change in the CUSIP numbers.

ARTICLE III.

PARTICULAR COVENANTS OF THE COMPANY

Section 3.1. Payment of Principal, Premium and Interest; Agreed Treatment of the Debentures.

(a) The Company
covenants and agrees that it will duly and punctually pay or cause to be paid the principal of and premium, if any, and interest and any Additional Interest and other payments on the Debentures at the place, at the respective times and in the manner
provided in this Indenture and the Debentures. Each installment of interest on the Debentures may be paid (i) by mailing checks for such interest payable to the order of the holders of Debentures entitled thereto as they appear on the registry
books of the Company if a request for a wire transfer has not been received by the Company or (ii) by wire transfer to any account with a banking institution located in the United States designated in writing by such Person to the paying agent
no later than the related record date. Notwithstanding the foregoing, so long as the holder of this Debenture is the Institutional Trustee, the payment of the principal of and interest on this Debenture will be made in immediately available funds at
such place and to such account as may be designated by the Institutional Trustee.

(b) The Company will treat the Debentures as
indebtedness, and the amounts payable in respect of the principal amount of such Debentures as interest, for all United States federal income tax purposes. All payments in respect of such Debentures will be made free and clear of United States
withholding tax to any beneficial owner thereof that has provided an Internal Revenue Service Form W8 BEN (or any substitute or successor form) establishing its non-United States status for United States federal income tax purposes.



18



---

(c) As of the date of this Indenture, the Company has no present intention to exercise its right under
Section 2.11 to defer payments of interest on the Debentures by commencing an Extension Period.

(d) As of the date of this Indenture,
the Company believes that the likelihood that it would exercise its right under Section 2.11 to defer payments of interest on the Debentures by commencing an Extension Period at any time during which the Debentures are outstanding is remote
because of the restrictions that would be imposed on the Companys ability to declare or pay dividends or distribution on, or to redeem, purchase or make a liquidation payment with respect to, any of its outstanding equity and on the
Companys ability to make any payments of principal of or interest on, or repurchase or redeem, any of its debt securities that rank pari passu in all respects with (or junior in interest to) the Debentures.

Section 3.2. Offices for Notices and Payments, etc. So long as any of the Debentures remain outstanding, the Company will maintain in
Hartford, Connecticut, an office or agency where the Debentures may be presented for payment, an office or agency where the Debentures may be presented for registration of transfer and for exchange as in this Indenture provided and an office or
agency where notices and demands to or upon the Company in respect of the Debentures or of this Indenture may be served. The Company will give to the Trustee written notice of the location of any such office or agency and of any change of location
thereof. Until otherwise designated from time to time by the Company in a notice to the Trustee, or specified as contemplated by Section 2.5, such office or agency for all of the above purposes shall be the office or agency of the Trustee. In
case the Company shall fail to maintain any such office or agency in Hartford, Connecticut, or shall fail to give such notice of the location or of any change in the location thereof, presentations and demands may be made and notices may be served

In addition to any such office or agency, the Company may from time to time designate one or more
offices or agencies outside Hartford, Connecticut, where the Debentures may be presented for registration of transfer and for exchange in the manner provided in this Indenture, and the Company may from time to time rescind such designation, as the
Company may deem desirable or expedient; provided, however, that no such designation or rescission shall in any manner relieve the Company of its obligation to maintain any such office or agency in Hartford, Connecticut, for the
purposes above mentioned. The Company will give to the Trustee prompt written notice of any such designation or rescission thereof.

Section 3.3. Appointments to Fill Vacancies in Trustees Office. The Company, whenever necessary to avoid or fill a vacancy in the office of Trustee, will appoint, in the manner provided in Section 6.9, a

(2) that it will give the Trustee prompt written notice of any failure by the Company (or by any other obligor on the Debentures) to make
any payment of the principal of and premium, if any, or interest, if any, on the Debentures when the same shall be due and payable; and

(3) that it will, at any time during the continuance of any Event of Default, upon the written request of the Trustee, forthwith pay to the Trustee all sums so held in trust by such paying agent.

writing of any failure to take such action and of any failure by the Company (or by any other obligor under the Debentures) to make any payment of the principal of and premium, if any, or interest or other payments, if any, on the Debentures when
the same shall become due and payable.

Whenever the Company shall have one or more paying agents for the Debentures, it will, on or prior
to each due date of the principal of and premium, if any, or interest, if any, on the Debentures deposit with a paying agent a sum sufficient to pay the principal, premium, interest or other payments so becoming due, such sum to be held in trust for
the benefit of the Persons entitled thereto and (unless such paying agent is the Trustee) the Company shall promptly notify the Trustee in writing of its action or failure to act.

discharge with respect to the Debentures, or for any other reason, pay, or direct any paying agent to pay to the Trustee all sums held in trust by the Company or any such paying agent, such sums to be held by the Trustee upon the trusts herein

Section 3.4 is subject to Sections 12.3 and 12.4.

the Trustee on or before 120 days after the end of each fiscal year, so long as Debentures are outstanding hereunder, a Certificate stating that in the course of the performance by the signers of their duties as officers of the Company they would
normally have knowledge of any default during such fiscal year by the Company in the performance of any covenants contained herein, stating whether or not they have knowledge of any such default and, if so, specifying each such default of which the
signers have knowledge and the nature and status thereof.

Debentures and the Trust is required to pay any additional taxes (including withholding taxes), duties, assessments a other governmental charges as a result of a Tax Event, the Company will pay such additional amounts (Additional
Sums) on the Debentures as shall be required so that the net amounts received and retained by the Trust after paying taxes (including withholding taxes), duties, assessments or other governmental charges will be equal to the amounts the
Trust would have received if no such taxes, duties, assessments or other governmental charges had been imposed. Whenever in this Indenture or the Debentures there is reference in any context to the payment of principal of or interest on the
Debentures, such mention shall be deemed to include mention of payments of the Additional Sums provided for in this paragraph to the extent that, in such context, Additional Sums are, were or would be payable in respect thereof pursuant to the

Section 3.7. Compliance with Consolidation Provisions. The Company will not, while any of the Debentures remain outstanding,
consolidate with, or merge into, or merge into itself, or sell a convey all or substantially all of its property to any other Person unless the provisions of Article XI hereof are complied with.

Section 3.8. Limitation on Dividends. If Debentures are initially issued to the Trust or a trustee of such Trust in connection with

to its payment of any obligation under the Capital Securities Guarantee, or (iii) the Company shall have given notice of its election to defer payments of interest on the Debentures by extending the interest payment period as provided herein

the form of stock, warrants, options or other rights where the dividend stock or the stock issuable upon exercise of such warrants, options or other rights is the same stock as that on which the dividend is being paid or ranks pari passu with
or junior to such stock and any cash payments in lieu of fractional shares issued in connection therewith, or (6) payments under the Capital Securities Guarantee).

Section 3.9. Covenants as to the Trust. For so long as the Trust Securities remain outstanding, the Company shall maintain 100% ownership of the Common Securities; provided, however,
that any permitted successor of the Company under this Indenture may succeed to the Companys ownership of such Common Securities. The Company, as owner of the Common Securities, shall, except in connection with a distribution of Debentures to

Debentures.

(a) on each regular record date for the Debentures, a list, in such form as the Trustee may reasonably require, of the names and addresses of the Securityholders of the Debentures as of such record date; and

(b) at such other times as the Trustee may request in writing, within 30 days after the receipt by the Company of any such request, a list
of similar form and content as of a date not more than 15 days prior to the time such list is furnished;

except that no such lists need be furnished under
this Section 4.1 so long as the Trustee is in possession thereof by reason of its acting as Debenture registrar.



22



---

Section 4.2. Preservation and Disclosure of Lists.

(a) The Trustee shall preserve, in as current a form as is reasonably practicable, all information as to the names and addresses of the holders of
Debentures (1) contained in the most recent list furnished to it as provided in Section 4.1 or (2) received by it in the capacity of Debentures registrar (if so acting) hereunder. The Trustee may destroy any list furnished to it as
provided in Section 4.1 upon receipt of a new list so furnished.

(b) In case three or more holders of Debentures (hereinafter
referred to as applicants) apply in writing to the Trustee and furnish to the Trustee reasonable proof that each such applicant has owned a Debenture for a period of at least 6 months preceding the date of such application, and
such application states that the applicants desire to communicate with other holders of Debentures with respect to their rights under this Indenture or under such Debentures and is accompanied by a copy of the form of proxy or other communication
which such applicants propose to transmit, then the Trustee shall within 5 Business Days after the receipt of such application, at its election, either:

(1) afford such applicants access to the information preserved at the time by the Trustee in accordance with the provisions of subsection (a) of this Section 4.2, or

(2) inform such applicants as to the approximate number of holders of Debentures whose names and addresses appear in the information
preserved at the time by the Trustee in accordance with the provisions of subsection (a) of this Section 4.2, and as to the approximate cost of mailing to such Securityholders the form of proxy or other communication, if any, specified in
such application.

If the Trustee shall elect not to afford such applicants access to such information, the Trustee shall, upon the written
request of such applicants, mail to each Securityholder whose name and address appear in the information preserved at the time by the Trustee in accordance with the provisions of subsection (a) of this Section 4.2 a copy of the form of
proxy or other communication which is specified in such request with reasonable promptness after a tender to the Trustee of the material to be mailed and of payment, or provision for the payment, of the reasonable expenses of mailing, unless within
five days after such tender, the Trustee shall mail to such applicants and file with the Securities and Exchange Commission, if permitted or required by applicable law, together with a copy of the material to be mailed, a written statement to the
effect that, in the opinion of the Trustee, such mailing would be contrary to the best interests of the holders of all Debentures, as the case may be, or would be in violation of applicable law. Such written statement shall specify the basis of such
opinion. If said Commission, as permitted or required by applicable law, after opportunity for a hearing upon the objections specified in the written statement so filed, shall enter an order refusing to sustain any of such objections or if, after
the entry of an order sustaining one or more of such objections, said Commission shall find, after notice and opportunity for hearing, that all the objections so sustained have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all such Securityholders with reasonable promptness after the entry of such order and the renewal of such tender; otherwise the Trustee shall be relieved of any obligation or duty to such applicants respecting their
application.

Trustee that neither the Company nor the Trustee nor any paying agent shall be held accountable by reason of the disclosure of any such information as to the names and addresses of the holders of Debentures in accordance with the provisions of
subsection (b) of this Section 4.2, regardless of the source from which such information was derived, and that the Trustee shall not be held accountable by reason of mailing any material pursuant to a request made under said subsection

ARTICLE V.

REMEDIES OF THE TRUSTEE AND SECURITYHOLDERS

UPON AN EVENT OF DEFAULT

Section 5.1. Events of Default. Event of Default, wherever used herein, means any one of the following events
(whatever the reason for such Event of Default and whether it shall be voluntary or involuntary or be effected by operation of law or pursuant to any judgment, decree or order of any court or any order, rule or regulation of any administrative or
governmental body):

(a) the Company defaults in the payment of any interest upon any Debenture when it becomes due and payable, and fails
to cure such default for a period of 30 days; provided,however, that a valid extension of an interest payment period by the Company in accordance with the terms of this Indenture shall not constitute a default in the payment of
interest for this purpose; or

(b) the Company defaults in the payment of all or any part of the principal of (or premium, if any, on) any
Debentures as and when the same shall become due and payable either at maturity, upon redemption, by declaration of acceleration or otherwise; or

(c) the Company defaults in the performance of, or breaches, any of its covenants of agreements in this Indenture or in the terms of the Debentures established as contemplated in this Indenture (other than a covenant or agreement a default
in whose performance or whose breach is elsewhere in this Section specifically dealt with), and continuance of such default or breach for a period of 60 days after there has been given, by registered or certified mail, to the Company by the Trustee
or to the Company and the Trustee by the holders of at least 25% in aggregate principal amount of the outstanding Debentures, a written notice specifying such default or breach and requiring it to be remedied and stating that such notice is a
Notice of Default hereunder; or

(d) a court of competent jurisdiction shall enter a decree or order for relief in respect of
the Company in an involuntary case under any applicable bankruptcy, insolvency, reorganization or other similar law now or hereafter in effect, or appointing a receiver, liquidator, assignee, custodian, trustee sequestrator (or similar official) of
the Company or for any substantial part of its property, or ordering the winding-up or liquidation of its affairs and such decree or order shall remain unstayed and in effect for period of 90 consecutive days; or



24



---

(e) the Company shall commence a voluntary case under any applicable bankruptcy, insolvency,
reorganization or other similar law now or hereafter in effect, shall consent to the entry of an order for relief in an involuntary case under any such law, or shall consent to the appointment of or taking possession by a receiver, liquidator,
assignee, trustee, custodian, sequestrator (or other similar official) of the Company or of any substantial part of its property, or shall make any general assignment for the benefit of creditors, or shall fail generally to pay its debts as they
become due; or

(f) the Trust shall have voluntarily or involuntarily liquidated, dissolved, wound-up its business or otherwise terminated
its existence except in connection with (i) the distribution of the Debentures to holders of such Trust Securities in liquidation of their interests in the Trust, (ii) the redemption of all of the outstanding Trust Securities or
(iii) certain mergers, consolidations or amalgamations, each as permitted by the Declaration.

If an Event of Default occurs and is
continuing with respect to the Debentures, then, and in each and every such case, unless the principal of the Debentures shall have already become due and payable, either the Trustee or the holders of not less than 25% in aggregate principal amount
of the Debentures then outstanding hereunder, by notice in writing to the Company (and to the Trustee if given by Securityholders), may declare the entire principal of the Debentures and the interest accrued thereon, if any, to be due and payable
immediately, and upon any such declaration the same shall become immediately due and payable.

The foregoing provisions, however, are
subject to the condition that if, at any time after the principal of the Debentures shall have been so declared due and payable, and before any judgment or decree for the payment of the moneys due shall have been obtained or entered as hereinafter
provided, (i) the Company shall pay or shall deposit with the Trustee a sum sufficient to pay all matured installments of interest upon all the Debentures and the principal of and premium, if any, on the Debentures which shall have become due
otherwise than by acceleration (with interest upon such principal and premium, if any, and Additional Interest) and such amount as shall be sufficient to cover reasonable compensation to the Trustee and each predecessor Trustee, their respective
agents, attorneys and counsel, and all other amounts due to the Trustee pursuant to Section 6.6, if any, and (ii) all Events of Default under this Indenture, other than the non-payment of the principal of or premium, if any, on Debentures
which shall have become due by acceleration, shall have been cured, waived or otherwise remedied as provided herein  then and in every such case the holders of a majority in aggregate principal amount of the Debentures then outstanding, by
written notice to the Company and to the Trustee, may waive all defaults and rescind and annul such declaration and its consequences, but no such waiver or rescission and annulment shall extend to or shall affect any subsequent default or shall
impair any right consequent thereon.

In case the Trustee shall have proceeded to enforce any right under this Indenture and such
proceedings shall have been discontinued or abandoned because of such rescission or annulment or for any other reason or shall have been determined adversely to the Trustee, then and in every such case the Company, the Trustee and the holders of the
Debentures shall be restored respectively to their several positions and rights hereunder, and all rights, remedies and powers of the Company, the Trustee and the holders of the Debentures shall continue as though no such proceeding had been taken.

Section 5.2. Payment of Debentures on Default; Suit Therefor. The Company covenant
that upon the occurrence of an Event of Default pursuant to Section 5.1(a) or Section 5.1(b) then, upon demand of the Trustee, the Company will pay to the Trustee, for the benefit of the holders of the Debentures the whole amount that then
shall have become due and payable on all Debentures for principal and premium, if any, or interest, or both, as the case may be, with Additional Interest accrued on the Debentures (to the extent that payment of such interest is enforceable under
applicable law and, if the Debentures are held by the Trust or a trustee of such Trust, without duplication of any other amounts paid by the Trust or a trustee in respect thereof); and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including a reasonable compensation to the Trustee, its agents, attorneys and counsel, and any other amounts due to the Trustee under Section 6.6. In case the Company shall fail forthwith to pay
such amounts upon such demand, the Trustee, in its own name and as trustee of an express trust, shall be entitled and empowered to institute any actions or proceedings at law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceeding to judgment or final decree, and may enforce any such judgment or final decree against the Company or any other obligor on such Debentures and collect in the manner provided by law out of the property of the
Company or any other obligor on such Debentures wherever situated the moneys adjudged or decreed to be payable.

In case there shall be
pending proceedings for the bankruptcy or for the reorganization of the Company or any other obligor on the Debentures under Bankruptcy Law, or in case a receiver or trustee shall have been appointed for the property of the Company or such other
obligor, or in the case of any other similar judicial proceedings relative to the Company or other obligor upon the Debentures, or to the creditors or property of the Company or such other obligor, the Trustee, irrespective of whether the principal
of the Debentures shall then be due and payable as therein expressed or by declaration or acceleration or otherwise and irrespective of whether the Trustee shall have made any demand pursuant to the provisions of this Section 5.2, shall be
entitled and empowered, by intervention in such proceedings or otherwise,



| | (i) | to file and prove a claim or claims for the whole amount of principal and interest owing and unpaid in respect of the Debentures,
| | --- | ---------------------------------------------------------------------------------------------------------------------------------



| | (ii) | in case of any judicial proceedings, to file such proofs of claim and other papers or documents as may be necessary or advisable in order to have the claims of the Trustee
(including any claim for reasonable compensation to the Trustee and each predecessor Trustee, and their respective agents, attorneys and counsel, and for reimbursement of all other amounts due to the Trustee under Section 6.6), and of the
Securityholders allowed in such judicial proceedings relative to the Company or any other obligor on the Debentures, or to the creditors or property of the Company or such other obligor, unless prohibited by applicable law and regulations, to vote
on behalf of the holders of the Debentures in any election of a trustee or a standby trustee in arrangement, reorganization, liquidation or other bankruptcy or insolvency proceedings or Person performing similar functions in comparable proceedings,
| | ---- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



| | (iii) | to collect and receive any moneys or other property payable or deliverable on any such claims, and
| | ----- | --------------------------------------------------------------------------------------------------



26



---

| | (iv) | to distribute the same after the deduction of its charges and expenses.
| | ---- | -----------------------------------------------------------------------

Any receiver, assignee or trustee in bankruptcy or reorganization is hereby authorized by each of the Securityholders to make such payments to the Trustee, and, in the event that the Trustee shall consent to the making of such payments
directly to the Securityholders, to pay to the Trustee such amounts as shall be sufficient to cover reasonable compensation to the Trustee, each predecessor Trustee and their respective agents, attorneys and counsel, and all other amounts due to the
Trustee under Section 6.6.

Nothing herein contained shall be construed to authorize the Trustee to authorize or consent to or accept
or adopt on behalf of any Securityholder any plan of reorganization, arrangement, adjustment or composition affecting the Debentures or the rights of any holder thereof or to authorize the Trustee to vote in respect of the claim of any
Securityholder in any such proceeding.

All rights of action and of asserting claims under this Indenture, or under any of the Debentures,
may be enforced by the Trustee without the possession of any of the Debentures, or the production thereof at any trial or other proceeding relative thereto, and any such suit or proceeding instituted by the Trustee shall be brought in its own name
as trustee of an express trust, and any recovery of judgment shall be for the ratable benefit of the holders of the Debentures.

In any
proceedings brought by the Trustee (and also any proceedings involving the interpretation of any provision of this Indenture to which the Trustee shall be a party), the Trustee shall be held to represent all the holders of the Debentures, and it
shall not be necessary to make any holders of the Debentures parties to any such proceedings.

Section 5.3. Application of
Moneys Collected by Trustee. Any moneys collected by the Trustee pursuant to this Article V shall be applied in the following order, at the date or dates fixed by the Trustee for the distribution of such moneys, upon presentation of the
several Debentures in respect of which moneys have been collected, and stamping thereon the payment, if only partially paid, and upon surrender thereof if fully paid:

First: To the payment of costs and expenses incurred by, and reasonable fees of, the Trustee, its agents, attorneys and counsel, and of all other amounts due to the Trustee under Section 6.6;

Second: To the payment of all Senior Indebtedness of the Company if and to the extent required by Article XV;

Third: To the payment of the amounts then due and unpaid upon Debentures for principal (and premium, if any), and interest on the Debentures, in respect
of which or for the benefit of which money has been collected, ratably, without preference or priority of any kind, according to the amounts due on such Debentures (including Additional Interest); and

Fourth: The balance, if any, to the Company.



27

Section 5.4. Proceedings by Securityholders. No holder of any Debenture shall have any
right to institute any suit, action or proceeding for any remedy hereunder, unless such holder previously shall have given to the Trustee written notice of an Event of Default with respect to the Debentures and unless the holders of not less than
25% in aggregate principal amount of the Debentures then outstanding shall have given the Trustee a written request to institute such action, suit or proceeding and shall have offered to the Trustee such reasonable indemnity as it may require
against the costs, expenses and liabilities to be incurred thereby, and the Trustee for 60 days after its receipt of such notice, request and offer of indemnity shall have failed to institute any such action, suit or proceeding.

Notwithstanding any other provisions in this Indenture, however, the right of any holder of any Debenture to receive payment of the principal of,
premium, if any, and interest, on such Debenture when due, or to institute suit for the enforcement of any such payment, shall not be impaired or affected without the consent of such holder and by accepting a Debenture hereunder it is expressly
understood, intended and covenanted by the taker and holder of every Debenture with every other such taker and holder and the Trustee, that no one or more holders of Debentures shall have any right in any manner whatsoever by virtue or by availing
itself of any provision of this Indenture to affect, disturb or prejudice the rights of the holders of any other Debentures, or to obtain or seek to obtain priority over or preference to any other such holder, or to enforce any right under this
Indenture, except in the manner herein provided and for the equal, ratable and common benefit of all holders of Debentures. For the protection and enforcement of the provisions of this Section, each and every Securityholder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

Section 5.5. Proceedings by Trustee. In case of an
Event of Default hereunder the Trustee may in its discretion proceed to protect and enforce the rights vested in it by this Indenture by such appropriate judicial proceedings as the Trustee shall deem most effectual to protect and enforce any of
such rights, either by suit in equity or by action at law or by proceeding in bankruptcy or otherwise, whether for the specific enforcement of any covenant or agreement contained in this Indenture or in aid of the exercise of any power granted in
this Indenture, or to enforce any other legal or equitable right vested in the Trustee by this Indenture or by law.

Section 5.6.
Remedies Cumulative and Continuing; Delay or Omission Not a Waiver. Except as otherwise provided in Section 2.6, all powers and remedies given by this Article V to the Trustee or to the Securityholders shall, to the extent permitted
by law, be deemed cumulative and not exclusive of any other powers and remedies available to the Trustee or the holders of the Debentures, by judicial proceedings or otherwise, to enforce the performance or observance of the covenants and agreements
contained in this Indenture or otherwise established with respect to the Debentures, and no delay or omission of the Trustee or of any holder of any of the Debentures to exercise any right, remedy or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right, remedy or power, or shall be construed to be a waiver of any such default or an acquiescence therein; and, subject to the provisions of Section 5.4, every power and remedy given
by this Article V or by law to the Trustee or to the Securityholders may be exercised from time to time, and as often as shall be deemed expedient, by the Trustee (in accordance with its duties under Section 6.1) or by the Securityholders.



28

Section 5.7. Direction of Proceedings and Waiver of Defaults by Majority of
Securityholders. The holders of a majority in aggregate principal amount of the Debentures affected (voting as one class) at the time outstanding shall have the right to direct the time, method, and place of conducting any proceeding for any
remedy available to the Trustee, or exercising any trust or power conferred on the Trustee with respect to such Debentures; provided,however, that (subject to the provisions of Section 6.1) the Trustee shall have the right to
decline to follow any such direction if the Trustee shall determine that the action so directed would be unjustly prejudicial to the holders not taking part in such direction or if the Trustee being advised by counsel determines that the action or
proceeding so directed may not lawfully be taken or if a Responsible Officer of the Trustee shall determine that the action or proceedings so directed would involve the Trustee in personal liability.

The holders of a majority in aggregate principal amount of the Debentures at the time outstanding may on behalf of the holders of all of the Debentures
waive (or modify any previously granted waiver of) any past default or Event of Default, and its consequences, except a default (a) in the payment of principal of, premium, if any, or interest on any of the Debentures, (b) in respect of
covenants or provisions hereof which cannot be modified or amended without the consent of the holder of each Debenture affected, or (c) in respect of the covenants contained in Section 3.9; provided, however, that if the
Debentures are held by the Trust or a trustee of such trust, such waiver or modification to such waiver shall not be effective until the holders of a majority in Liquidation Amount of Trust Securities of the Trust shall have consented to such waiver
or modification to such waiver, provided, further, that if the consent of the holder of each outstanding Debenture is required, such waiver shall not be effective until each holder of the Trust Securities of the Trust shall have
consented to such waiver. Upon any such waiver, the default covered thereby shall be deemed to be cured for all purposes of this Indenture and the Company, the Trustee and the holders of the Debentures shall be restored to their former positions and
rights hereunder, respectively; but no such waiver shall extend to any subsequent or other default or Event of Default of impair any right consequent thereon. Whenever any default or Event of Default hereunder shall have been waived as permitted by
this Section, said default or Event of Default shall for all purposes of the Debentures and this Indenture be deemed to have been cured and to be not continuing.

Section 5.8. Notice of Defaults. The Trustee shall, within 90 days after the actual knowledge by a Responsible Officer of the Trustee of the occurrence of a default with respect to the Debentures,
mail to all Securityholders, as the names and addresses of such holders appear upon the Debenture Register, notice of all defaults with respect to the Debentures known to the Trustee, unless such defaults shall have been cured before the giving of
such notice (the term defaults for the purpose of this Section 5.8 being hereby defined to be the events specified in clauses (a), (b), (c), (d), (e) and (f) of Section 5.1, not including periods of grace, if any,
provided for therein); provided, however, that, except in the case of default in the payment of the principal of, premium, if any, or interest on any of the Debentures, the Trustee shall be protected in withholding such notice if and
so long as a Responsible Officer of the Trustee in good faith determines that the withholding of such notice is in the interests of the Securityholders.

Section 5.9. Undertaking to Pay Costs. All parties to this Indenture agree, and each holder of any Debenture by his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under

undertaking to pay the costs of such suit, and that such court may in its discretion assess reasonable costs, including reasonable attorneys fees and expenses, against any party litigant in such suit, having due regard to the merits and good

of Securityholders, holding in the aggregate more than 10% in principal amount of the Debentures outstanding, or to any suit instituted by any Securityholder for the enforcement of the payment of the principal of (or premium, if any) or interest on
any Debenture against the Company on or after the same shall have become due and payable.

ARTICLE VI.

CONCERNING THE TRUSTEE

Section 6.1. Duties and Responsibilities of Trustee. With respect to the holders of Debentures issued hereunder, the Trustee, prior to the occurrence of an Event of Default with respect to the Debentures and after the
curing or waiving of all Events of Default which may have occurred, with respect to the Debentures, undertakes to perform such duties and only such duties as are specifically set forth in this Indenture, and no implied covenants shall be read into
this Indenture against the Trustee. In case an Event of Default with respect to the Debentures has occurred (which has not been cured a waived), the Trustee shall exercise such of the rights and powers vested in it by this Indenture, and use the
same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs.

No provision of this Indenture shall be construed to relieve the Trustee from liability for its own negligent action, its own negligent failure to act or its own willful misconduct, except that:

(a) prior to the occurrence of an Event of Default with respect to Debentures and after the curing or waiving of all Events of Default which may have
occurred

(1) the duties and obligations of the Trustee with respect to Debentures shall be determined solely by the express
provisions of this Indenture, and the Trustee shall not be liable except for the performance of such duties and obligations with respect to the Debentures as are specifically set forth in this Indenture, and no implied covenants or obligations shall
be read into this Indenture against the Trustee, and

(2) in the absence of bad faith on the part of the Trustee, the
Trustee may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Trustee and conforming to the requirements of this Indenture; but, in the case
of any such certificates or opinions which by any provision hereof are specifically required to be furnished to the Trustee, the Trustee shall be under a duty to examine the same to determine whether or not they conform to the requirements of this
Indenture;



30



---

(b) the Trustee shall not be liable for any error of judgment made in good faith by a Responsible Officer
or Officers of the Trustee, unless it shall be proved that the Trustee was negligent it ascertaining the pertinent facts; and

(c) the
Trustee shall not be liable with respect to any action taken or omitted to be taken by it in good faith, in accordance with the direction of the Securityholders pursuant to Section 5.7, relating to the time, method and place of conducting any
proceeding for any remedy available to the Trustee, or exercising any trust or power conferred upon the Trustee, under this Indenture.

None of the provisions contained in this Indenture shall require the Trustee to expend or risk its own funds or otherwise incur personal financial liability in the performance of any of its duties or in the exercise of any of its rights or
powers, if there is ground for believing that the repayment of such funds or liability is not assured to it under the terms of this Indenture or indemnity satisfactory to the Trustee against such risk is not reasonably assured to it.

Section 6.2. Reliance on Documents, Opinions, etc. Except as otherwise provided in Section 6.1:

(a) the Trustee may conclusively rely and shall be fully protected in acting or refraining from acting upon any resolution, certificate, statement,
instrument, opinion, report, notice, request, consent, order, bond, note, debenture or other paper or document believed by it to be genuine and to have been signed or presented by the proper party or parties;

(b) any request, direction, order or demand of the Company mentioned herein shall be sufficiently evidenced by an Officers Certificate (unless
other evidence in respect thereof be herein specifically prescribed); and any Board Resolution may be evidenced to the Trustee by a copy thereof certified by the Secretary or an Assistant Secretary of the Company;

(c) the Trustee may consult with counsel of its selection and any advice or Opinion of Counsel shall be full and complete authorization and protection in
respect of any action taken, suffered or omitted by it hereunder in good faith and in accordance with such advice or Opinion of Counsel;

(d) the Trustee shall be under no obligation to exercise any of the rights or powers vested in it by this Indenture at the request, order or direction of any of the Securityholders, pursuant to the provisions of this Indenture, unless such
Securityholders shall have offered to the Trustee reasonable security or indemnity against the costs, expenses and liabilities which may be incurred therein or thereby;

(e) the Trustee shall not be liable for any action taken or omitted by it in good faith and believed by it to be authorized or within the discretion or rights or powers conferred upon it by this Indenture; nothing
contained herein shall, however, relieve the Trustee of the obligation, upon the occurrence of an Event of Default with respect to the Debentures (that has not been cured or waived) to exercise with respect to Debentures such of the rights and
powers vested in it by this Indenture, and to use the same degree of care and skill in their exercise, as a prudent man would exercise or use under the circumstances in the conduct of his own affairs;



31



---

(f) the Trustee shall not be bound to make any investigation into the facts or matters stated in any
resolution, certificate, statement, instrument, opinion, report, notice, request, consent, order, approval, bond, debenture, coupon or other paper or document, unless requested in writing to do so by the holders of not less than a majority in
aggregate principal amount of the outstanding Debentures affected thereby; provided, however, that if the payment within a reasonable time to the Trustee of the costs, expenses or liabilities likely to be incurred by it in the making
of such investigation is, in the opinion of the Trustee, not reasonably assured to the Trustee by the security afforded to it by the terms of this Indenture, the Trustee may require reasonable indemnity against such expense or liability as a
condition to so proceeding;

(g) the Trustee may execute any of the trusts or powers hereunder or perform any duties hereunder either
directly or by or through agents (including any Authenticating Agent) or attorneys, and the Trustee shall not be responsible for any misconduct or negligence on the part of any such agent or attorney appointed by it with due care; and

(h) with the exceptions of defaults under Sections 5.1(a) or 5.1(b), the Trustee shall not be charged with knowledge of any Default or Event of Default
with respect to the Debentures unless a written notice of such Default or Event of Default shall have been given to the Trustee by the Company or any other obligor on the Debentures or by any holder of the Debentures.

Section 6.3. No Responsibility for Recitals, etc. The recitals contained herein and in the Debentures (except in the certificate of
authentication of the Trustee or the Authenticating Agent) shall be taken as the statements of the Company, and the Trustee and the Authenticating Agent assume no responsibility for the correctness of the same. The Trustee and the Authenticating
Agent make no representations as to the validity or sufficiency of this Indenture or of the Debentures. The Trustee and the Authenticating Agent shall not be accountable for the use or application by the Company of any Debentures or the proceeds of
any Debentures authenticated and delivered by the Trustee or the Authenticating Agent in conformity with the provisions of this Indenture.

Section 6.4. Trustee, Authenticating Agent, Paying Agents, Transfer Agents or Registrar May Own Debentures. The Trustee or any Authenticating Agent or any paying agent or any transfer agent or any Debenture registrar, in
its individual or any other capacity, may become the owner or pledgee of Debentures with the same rights it would have if it were not Trustee, Authenticating Agent, paying agent, transfer agent or Debenture registrar.

Section 6.5. Moneys to be Held in Trust. Subject to the provisions of Section 12.4, all moneys received by the Trustee or any
paying agent shall, until used or applied as herein provided, be held in trust for the purpose for which they were received, but need not be segregated from other funds except to the extent required by law. The Trustee and any paying agent shall be
under no liability for interest on any money received by it hereunder except as otherwise agreed in writing with the Company. So long as no Event of Default shall have occurred and be continuing, all interest allowed on any such moneys shall be paid
from time to time upon the written order of the Company, signed by the Chairman of the Board of Directors, the Chief Executive Officer, the President, a Managing Director, a Vice President, the Treasurer or an Assistant Treasurer of the Company.

Section 6.6. Compensation and Expenses of Trustee. The Company covenants and agrees to
pay or reimburse the Trustee upon its request for all reasonable expenses, disbursements and advances incurred or made by the Trustee in accordance with any of the provisions of this Indenture (including the reasonable compensation and the expenses
and disbursements of its counsel and of all Persons not regularly in its employ) except any such expense, disbursement or advance as may arise from its negligence or willful misconduct. For purposes of clarification, this Section 6.6 does not
contemplate the payment by the Company of acceptance or annual administration fees owing to the Trustee pursuant to the services to be provided by the Trustee under this Indenture or the fees and expenses of the Trustees counsel in connection
with the closing of the transactions contemplated by this Indenture. The Company also covenants to indemnify each of the Trustee or any predecessor Trustee (and its officers, agents, directors and employees) for, and to hold it harmless against, any
and all loss, damage, claim, liability or expense including taxes (other than taxes based on the income of the Trustee) incurred without negligence or willful misconduct on the part of the Trustee and arising out of or in connection with the
acceptance or administration of this trust, including the costs and expenses of defending itself against any claim of liability. The obligations of the Company under this Section 6.6 to compensate and indemnify the Trustee and to pay or
reimburse the Trustee for expenses, disbursements and advances shall constitute additional indebtedness hereunder. Such additional indebtedness shall be secured by a lien prior to that of the Debentures upon all property and funds held or collected
by the Trustee as such, except funds held in trust for the benefit of the holders of particular Debentures.

Without prejudice to any other
rights available to the Trustee under applicable law, when the Trustee incurs expenses or renders services in connection with an Event of Default specified in Section 5.1(d), Section 5.1(e) or Section 5.1(f), the expenses (including
the reasonable charges and expenses of its counsel) and the compensation for the services are intended to constitute expenses of administration under any applicable federal or state bankruptcy, insolvency or other similar law.

The provisions of this Section shall survive the resignation or removal of the Trustee and the defeasance or other termination of this Indenture.

Notwithstanding anything in this Indenture or any Debenture to the contrary, the Trustee shall have no obligation whatsoever to advance
funds to pay any principal of or interest on or other amounts with respect to the Debentures or otherwise advance funds to or on behalf of the Company.

Section 6.7. Officers Certificate as Evidence. Except as otherwise provided in Sections 6.1 and 6.2, whenever in the administration of the provisions of this Indenture the Trustee shall deem
it necessary or desirable that a matter be proved or established prior to taking or omitting any action hereunder, such matter (unless other evidence in respect thereof be herein specifically prescribed) may, in the absence of negligence or willful
misconduct on the part of the Trustee, be deemed to be conclusively proved and established by an Officers Certificate delivered to the Trustee, and such certificate, in the absence of negligence or willful misconduct on the part of the
Trustee, shall be full warrant to the Trustee for any action taken or omitted by it under the provisions of this Indenture upon the faith thereof.

Section 6.8. Eligibility of Trustee. The Trustee hereunder shall at all times be a
corporation organized and doing business under the laws of the United States of America or any state or territory thereof or of the District of Columbia or a corporation or other Person authorized under such laws to exercise corporate trust powers,
having (or whose obligations under this Indenture are guaranteed by an affiliate having) a combined capital and surplus of at least 50 million U.S. dollars ($50,000,000.00) and subject to supervision or examination by federal, state,
territorial, or District of Columbia authority. If such corporation publishes reports of condition at least annually, pursuant to law or to the requirements of the aforesaid supervising or examining authority, then for the purposes of this
Section 6.8 the combined capital and surplus of such corporation shall be deemed to be its combined capital and surplus as set forth in its most recent records of condition so published.

The Company may not, nor may any Person directly or indirectly controlling, controlled by, or under common control with the Company, serve as Trustee.

In case at any time the Trustee shall cease to be eligible in accordance with the provisions of this Section 6.8, the Trustee shall
resign immediately in the manner and with the effect specified in Section 6.9.

If the Trustee has or shall acquire any
conflicting interest within the meaning of §310(b) of the Trust Indenture Act of 1939, the Trustee shall either eliminate such interest or resign, to the extent and in the manner described by this Indenture.

Section 6.9. Resignation or Removal of Trustee.

(a) The Trustee, or any trustee or trustees hereafter appointed, may at any time resign by giving written notice of such resignation to the Company and by mailing notice thereof, at the Companys expense, to the
holders of the Debentures at their addresses as they shall appear on the Debenture Register. Upon receiving such notice of resignation, the Company shall promptly appoint a successor trustee or trustees by written instrument, in duplicate, executed
by order of its Board of Directors, one copy of which instrument shall be delivered to the resigning Trustee and one copy to the successor Trustee. If no successor Trustee shall have been so appointed and have accepted appointment within 30 days
after the mailing of such notice of resignation to the affected Securityholders, the resigning Trustee may petition any court of competent jurisdiction for the appointment of a successor Trustee, or any Securityholder who has been a bona fide holder
of a Debenture or Debentures for at least six months may, subject to the provisions of Section 5.9, on behalf of himself and all others similarly situated, petition any such court for the appointment of a successor Trustee. Such court may
thereupon, after such notice, if any, as it may deem proper and prescribe, appoint a successor Trustee.

(b) In case at any time any of the
following shall occur 

(1) the Trustee shall fail to comply with the provisions of Section 6.8 after written
request therefor by the Company or by any Securityholder who has been a bona fide holder of a Debenture or Debentures for at least 6 months, or



34



---

(2) the Trustee shall cease to be eligible in accordance with the provisions of
Section 6.8 and shall fail to resign after written request therefor by the Company or by any such Securityholder, or

(3) the Trustee shall become incapable of acting, or shall be adjudged as bankrupt or insolvent, or a receiver of the Trustee or of its property shall be appointed, or any public officer shall take charge or control of the Trustee or of its
property or affairs for the purpose of rehabilitation, conservation or liquidation,

then, in any such case, the Company may remove the Trustee and appoint
a successor Trustee by written instrument, in duplicate, executed by order of the Board of Directors, one copy of which instrument shall be delivered to the Trustee so removed and one copy to the successor Trustee, or, subject to the provisions of
Section 5.9, any Securityholder who has been a bona fide holder of a Debenture or Debentures for at least 6 months may, on behalf of himself and all others similarly situated, petition any court of competent jurisdiction for the removal of the
Trustee and the appointment of a successor Trustee. Such court may thereupon, after such notice, if any, as it may deem proper and prescribe, remove the Trustee and appoint successor Trustee.

(c) Upon prior written notice to the Company and the Trustee, the holders of a majority in aggregate principal amount of the Debentures at the time
outstanding may at any time remove the Trustee and nominate a successor Trustee, which shall be deemed appointed as successor Trustee unless within 10 Business Days after such nomination the Company objects thereto, in which case, or in the case of
a failure by such holders to nominate a successor Trustee, the Trustee so removed or any Securityholder, upon the terms and conditions and otherwise as in subsection (a) of this Section 6.9 provided, may petition any court of competent
jurisdiction for an appointment of a successor.

(d) Any resignation or removal of the Trustee and appointment of a successor Trustee
pursuant to any of the provisions of this Section shall become effective upon acceptance of appointment by the successor Trustee as provided in Section 6.10.

Section 6.10. Acceptance by Successor Trustee. Any successor Trustee appointed as provided in Section 6.9 shall execute, acknowledge and deliver to the Company and to its predecessor Trustee an
instrument accepting such appointment hereunder, and thereupon the resignation or removal of the retiring Trustee shall become effective and such successor Trustee, without any further act, deed or conveyance, shall become vested with all the
rights, powers, duties and obligations with respect to the Debentures of its predecessor hereunder, with like effect as if originally named as Trustee herein; but, nevertheless, on the written request of the Company or of the successor Trustee, the
Trustee ceasing to act shall, upon payment of any amounts then due it pursuant to the provisions of Section 6.6, execute and deliver an instrument transferring to such successor Trustee all the rights and powers of the Trustee so ceasing to act
and shall duly assign, transfer and deliver to such successor Trustee all property and money held by such retiring Trustee thereunder. Upon request of any such successor Trustee, the Company shall execute any and all instruments in writing for more
fully and certainly vesting in and confirming to such successor Trustee all such rights and powers. Any Trustee ceasing to act shall, nevertheless, retain a lien upon all property or funds held or collected by such Trustee to secure any amounts then
due it pursuant to the provisions of Section 6.6.



35



---

If a successor Trustee is appointed, the Company, the retiring Trustee and the successor Trustee shall
execute and deliver an indenture supplemental hereto which shall contain such provisions as shall be deemed necessary or desirable to confirm that all the rights, powers, trusts and duties of the retiring Trustee with respect to the Debentures as to
which the predecessor Trustee is not retiring shall continue to be vested in the predecessor Trustee, and shall add to or change any of the provisions of this Indenture as shall be necessary to provide for or facilitate the administration of the
Trust hereunder by more than one Trustee, it being understood that nothing herein or in such supplemental indenture shall constitute such Trustees co-trustees of the same trust and that each such Trustee shall be Trustee of a trust or trusts
hereunder separate and apart from any trust or trusts hereunder administered by any other such Trustee.

No successor Trustee shall accept
appointment as provided in this Section unless at the time of such acceptance such successor Trustee shall be eligible under the provisions of Section 6.8.

In no event shall a retiring Trustee be liable for the acts or omissions of any successor Trustee hereunder.

Upon acceptance of appointment by a successor Trustee as provided in this Section 6.10, the Company shall mail notice of the succession of such Trustee hereunder to the holders of Debentures at their addresses as they shall appear on
the Debenture Register. If the Company fails to mail such notice within 10 Business Days after the acceptance of appointment by the successor Trustee, the successor Trustee shall cause such notice to be mailed at the expense of the Company.

Section 6.11. Succession by Merger, etc. Any corporation into which the Trustee may be merged or converted or with
which it may be consolidated, or any corporation resulting from any merger, conversion or consolidation to which the Trustee shall be a party, or any corporation succeeding to all or substantially all of the corporate trust business of the Trustee,
shall be the successor of the Trustee hereunder without the execution or filing of any paper or any further act on the part of any of the parties hereto; provided such corporation shall be otherwise eligible and qualified under this Article.

In case at the time such successor to the Trustee shall succeed to the trusts created by this Indenture any of the Debentures shall have
been authenticated but not delivered, any such successor to the Trustee may adopt the certificate of authentication of any predecessor Trustee, and deliver such Debentures so authenticated; and in case at that time any of the Debentures shall not
have been authenticated, any successor to the Trustee may authenticate such Debentures either in the name of any predecessor hereunder or in the name of the successor Trustee; and in all such cases such certificates shall have the full force which
it is anywhere in the Debentures or in this Indenture provided that the certificate of the Trustee shall have; provided, however, that the right to adopt the certificate of authentication of any predecessor Trustee or authenticate
Debentures in the name of any predecessor Trustee shall apply only to its successor or successors by merger, conversion or consolidation.



36



---

Section 6.12. Authenticating Agents. There may be one or more Authenticating Agents
appointed by the Trustee upon the request of the Company with power to act on its behalf and subject to its direction in the authentication and delivery of Debentures issued upon exchange or registration of transfer thereof as fully to all intents
and purposes as though any such Authenticating Agent had been expressly authorized to authenticate and deliver Debentures; provided, however, that the Trustee shall have no liability to the Company for any acts or omissions of the
Authenticating Agent with respect to the authentication and delivery of Debentures. Any such Authenticating Agent shall at all times be a corporation organized and doing business under the laws of the United States or of any state or territory
thereof or of the District of Columbia authorized under such laws to act as Authenticating Agent, having a combined capital and surplus of at least $50,000,000.00 and being subject to supervision or examination by federal, state, territorial or
District of Columbia authority. If such corporation publishes reports of condition at least annually pursuant to law or the requirements of such authority, then for the purposes of this Section 6.12 the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth in its most recent report of condition so published. If at any time an Authenticating Agent shall cease to be eligible in accordance with the provisions of this Section,
it shall resign immediately in the manner and with the effect herein specified in this Section.

Any corporation into which any
Authenticating Agent may be merged or converted or with which it may be consolidated, or any corporation resulting from any merger, consolidation or conversion to which any Authenticating Agent shall be a party, or any corporation succeeding to all
or substantially all of the corporate trust business of any Authenticating Agent, shall be the successor of such Authenticating Agent hereunder, if such successor corporation is otherwise eligible under this Section 6.12 without this execution
or filing of any paper or any further act on the part of the parties hereto or such Authenticating Agent.

Any Authenticating Agent may at
any time resign by giving written notice of resignation to the Trustee and to the Company. The Trustee may at any time terminate the agency of any Authenticating Agent with respect to the Debentures by giving written notice of termination to such
Authenticating Agent and to the Company. Upon receiving such a notice of resignation or upon such a termination, or in case at any time any Authenticating Agent shall cease to be eligible under this Section 6.12, the Trustee may, and upon the
request of the Company shall, promptly appoint a successor Authenticating Agent eligible under this Section 6.12, shall give written notice of such appointment to the Company and shall mail notice of such appointment to all holders of
Debentures as the names and addresses of such holders appear on the Debenture Register. Any successor Authenticating Agent upon acceptance of its appointment hereunder shall become vested with all rights, powers, duties and responsibilities with
respect to the Debentures of its predecessor hereunder, with like effect as if originally named as Authenticating Agent herein.

The
Company agrees to pay to any Authenticating Agent from time to time reasonable compensation for its services. Any Authenticating Agent shall have no responsibility or liability for any action taken by it as such in accordance with the directions of
the Trustee.

ARTICLE VII.

CONCERNING THE SECURITYHOLDERS

Section 7.1. Action by Securityholders.
Whenever in this Indenture it is provided that the holders of a specified percentage in aggregate principal amount of the Debentures may take any action (including the making of any demand or request, the giving of any notice, consent or waiver or
the taking of any other action) the fact that at the time of taking any such action the holders of such specified percentage have joined therein may be evidenced (a) by any instrument or any number of instruments of similar tenor executed by
such Securityholders in person or by agent or proxy appointed in writing, or (b) by the record of such holders of Debentures voting in favor thereof at any meeting of such Securityholders duly called and held in accordance with the provisions
of Article VIII, or (c) by combination of such instrument or instruments and any such record of such a meeting of such Securityholders or (d) by any other method the Trustee deems satisfactory.

If the Company shall solicit from the Securityholders any request, demand, authorization direction, notice, consent, waiver or other action or revocation
of the same, the Company may, at its option, as evidenced by an Officers Certificate, fix in advance a record date for such Debentures for the determination of Securityholders entitled to give such request, demand, authorization, direction,
notice, consent, waiver or other action or revocation of the same, but the Company shall have no obligation to do so. If such a record date is fixed, such request, demand, authorization, direction, notice, consent, waiver or other action or
revocation of the same may be given before or after the record date, but only the Securityholders of record at the close of business on the record date shall be deemed to be Securityholders for the purposes of determining whether Securityholders of
the requisite proportion of outstanding Debentures have authorized or agreed or consented to such request, demand, authorization, direction, notice, consent, waiver or other action or revocation of the same, and for that purpose the outstanding
Debentures shall be computed as of the record date; provided,however, that no such authorization agreement or consent by such Securityholders on the record date shall be deemed effective unless it shall become effective pursuant to
the provisions of this Indenture not later than 6 months after the record date.

Section 7.2. Proof of Execution by
Securityholders. Subject to the provisions of Section 6.1, 6.2 and 8.5, proof of the execution of any instrument by a Securityholder or his agent or proxy shall be sufficient if made in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee or in such manner as shall be satisfactory to the Trustee. The ownership of Debentures shall be proved by the Debenture Register or by a certificate of the Debenture registrar. The Trustee may require
such additional proof of any matter referred to in this Section as it shall deem necessary.

The record of any Securityholders
meeting shall be proved in the manner provided in Section 8.6.

Section 7.3. Who Are Deemed Absolute Owners. Prior
to due presentment for registration of transfer of any Debenture, the Company, the Trustee, any Authenticating Agent, any paying agent, any transfer agent and any Debenture registrar may deem the Person in whose name such Debenture shall be
registered upon the Debenture Register to be, and may treat him as,



38



---

the absolute owner of such Debenture (whether or not such Debenture shall be overdue) for the purpose of receiving payment of or on account of the principal
of, premium, if any, and interest on such Debenture and for all other purposes; and neither the Company nor the Trustee nor any Authenticating Agent nor any paying agent nor any transfer agent nor any Debenture registrar shall be affected by any
notice to the contrary. All such payments so made to any holder for the time being or upon his order shall be valid, and, to the extent of the sum or sums so paid, effectual to satisfy and discharge the liability for moneys payable upon any such
Debenture.

Section 7.4. Debentures Owned by Company Deemed Not Outstanding. In determining whether the holders of the
requisite aggregate principal amount of Debentures have concurred in any direction, consent or waiver under this Indenture, Debentures which are owned by the Company or any other obligor on the Debentures or by any Person directly or indirectly
controlling or controlled by or under direct or indirect common control with the Company or any other obligor on the Debentures shall be disregarded and deemed not to be outstanding for the purpose of any such determination; provided,
however, that for the purposes of determining whether the Trustee shall be protected in relying on any such direction, consent or waiver, only Debentures which a Responsible Officer of the Trustee actually knows are so owned shall be so
disregarded. Debentures so owned which have been pledged in good faith may be regarded as outstanding for the purposes of this Section 7.4 if the pledgee shall establish to the satisfaction of the Trustee the pledgees right to vote such
Debentures and that the pledgee is not the Company or any such other obligor or Person directly or indirectly controlling or controlled by or under direct or indirect common control with the Company or any such other obligor. In the case of a
dispute as to such right, any decision by the Trustee taken upon the advice of counsel shall be full protection to the Trustee.

Section 7.5. Revocation of Consents; Future Holders Bound. At any time prior to (but not after) the evidencing to the Trustee, as provided in Section 7.1, of the taking of any action by the holders of the percentage
in aggregate principal amount of the Debentures specified in this Indenture in connection with such action, any holder (in cases where no record date has been set pursuant to Section 7.1) or any holder as of an applicable record date (in cases
where a record date has been set pursuant to Section 7.1) of a Debenture (or any Debenture issued in whole or in part in exchange or substitution therefor) the serial number of which is shown by the evidence to be included in the Debentures the
holders of which have consented to such action may, by filing written notice with the Trustee at the Principal Office of the Trustee and upon proof of holding as provided in Section 7.2, revoke such action so far as concerns such Debenture (or
so far as concerns the principal amount represented by any exchanged or substituted Debenture). Except as aforesaid any such action taken by the holder of any Debenture shall be conclusive and binding upon such holder and upon all future holders and
owners of such Debenture, and of any Debenture issued in exchange or substitution therefor or on registration of transfer thereof, irrespective of whether or not any notation in regard thereto is made upon such Debenture or any Debenture issued in
exchange or substitution therefor.

Section 14.11. Assignment. The Company will have the right at all times to assign any of its rights or obligations under this
Indenture to a direct or indirect wholly owned Subsidiary of the Company, provided that, in the event of any such assignment, the Company will remain liable for all such obligations. Subject to the foregoing, this Indenture is binding upon and
inures to the benefit of the parties hereto and their respective successors and assigns. This Indenture may not otherwise be assignee by the parties hereto.

Section 14.12. Acknowledgment of Rights. The Company agrees that, with respect to and Debentures held by the Trust or the Institutional Trustee of the Trust, if the Institutional Trustee of the
Trust fails to enforce its rights under this Indenture as the holder of Debentures held as the assets of such Trust after the holders of a majority in Liquidation Amount of the Capital Securities of such Trust have so directed such Institutional
Trustee, a holder of record of such Capital Securities may, to the fullest extent permitted by law, institute legal proceedings directly against the Company to enforce such Institutional Trustees rights under this Indenture without first
instituting any legal proceedings against such trustee or any other Person. Notwithstanding the foregoing, if an Event of Default has occurred and is continuing and such event is attributable to the failure of the Company to pay interest (or
premium, if any) or principal on the Debentures on the date such interest (or premium, if any) or principal is otherwise payable (or in the case of redemption, on the redemption date), the Company agrees



51



---

that a holder of record of Capital Securities of the Trust may directly institute a proceeding against the Company for enforcement of payment to such holder
directly of the principal of (or premium, if any) or interest on the Debentures having an aggregate principal amount equal to the aggregate Liquidation Amount of the Capital Securities of such holder on or after the respective due date specified in
the Debentures.

ARTICLE XV.

SUBORDINATION OF DEBENTURES

Section 15.1. Agreement to Subordinate. The Company covenants and
agrees, and each holder of Debentures by such Securityholders acceptance thereof likewise covenants and agrees, that all Debentures shall be issued subject to the provisions of this Article XV; and each holder of a Debenture whether upon
original issue or upon transfer or assignment thereof, accepts and agrees to be bound by such provisions.

The payment by the Company of
the principal of, and premium, if any, and interest on all Debentures shall, to the extent and in the manner hereinafter set forth, be subordinated and junior in right of payment to the prior payment in full of all Senior Indebtedness of the
Company, whether outstanding at the date of this Indenture or thereafter incurred.

No provision of this Article XV shall prevent the
occurrence of any default or Event of Default hereunder.

Section 15.2. Default on Senior Indebtedness. In the event and
during the continuation of any default by the Company in the payment of principal, premium, interest or any other payment due on any Senior Indebtedness of the Company following any grace period, or in the event that the maturity of any Senior
Indebtedness of the Company has been accelerated because of a default and such acceleration has not been rescinded or canceled and such Senior Indebtedness has not been paid in full, then, in either case, no payment shall be made by the Company with
respect to the principal (including redemption) of, or premium, if any, or interest on the Debentures.

In the event that, notwithstanding
the foregoing, any payment shall be received by the Trustee when such payment is prohibited by the preceding paragraph of this Section 15.2, such payment shall, subject to Section 15.7, be held in trust for the benefit of, and shall be
paid over or delivered to, the holders of Senior Indebtedness or their respective representatives, or to the trustee or trustees under any indenture pursuant to which any of such Senior Indebtedness may have been issued, as their respective
interests may appear, but only to the extent that the holders of the Senior Indebtedness (or their representative or representatives or a trustee) notify the Trustee in writing within 90 days of such payment of the amounts then due and owing on the
Senior Indebtedness and only the amounts specified in such notice to the Trustee shall be paid to the holders of Senior Indebtedness.

Section 15.3. Liquidation, Dissolution, Bankruptcy. Upon any payment by the Company or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to creditors upon any
dissolution or winding-up or liquidation or reorganization of the Company, whether voluntary or involuntary or in bankruptcy, insolvency,



52



---

receivership or other proceedings, all amounts due upon all Senior Indebtedness of the Company shall first be paid in full, or payment thereof provided for
in money in accordance with its terms, before any payment is made by the Company, on account of the principal (and premium, if any) or interest on the Debentures. Upon any such dissolution or winding-up or liquidation or reorganization, any payment
by the Company, or distribution of assets of the Company of any kind or character, whether in cash, property or securities, to which the Securityholders or the Trustee would be entitled to receive from the Company, except for the provisions of this
Article XV, shall be paid by the Company, or by any receiver, trustee in bankruptcy, liquidating trustee, agent or other Person making such payment or distribution, or by the Securityholders or by the Trustee under this Indenture if received by them
or it, directly to the holders of Senior Indebtedness (pro rata to such holders on the basis of the respective amounts of Senior Indebtedness held by such holders, as calculated by the Company) or their representative or representatives, or
to the trustee or trustees under any indenture pursuant to which any instruments evidencing such Senior Indebtedness may have been issued, as their respective interests may appear, to the extent necessary to pay such Senior Indebtedness in full, in
money or moneys worth, after giving effect to any concurrent payment or distribution to or for the holders of such Senior Indebtedness, before any payment or distribution is made to the Securityholders or to the Trustee.

In the event that, notwithstanding the foregoing, any payment or distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing, shall be received by the Trustee before all Senior Indebtedness is paid in full, or provision is made for such payment in money in accordance with its terms, such payment or distribution shall be
held in trust for the benefit of and shall be paid over or delivered to the holders of such Senior Indebtedness or their representative or representatives, or to the trustee or trustees under any indenture pursuant to which any instruments
evidencing such Senior Indebtedness may have been issued, as their respective interests may appear, as calculated by the Company, for application to the payment of all Senior Indebtedness, remaining unpaid to the extent necessary to pay such Senior
Indebtedness in full in money in accordance with its terms, after giving effect to any concurrent payment or distribution to or for the benefit of the holders of such Senior Indebtedness.

For purposes of this Article XV, the words cash, property or securities shall not be deemed to include shares of stock of the Company as
reorganized or readjusted, or securities of the Company or any other corporation provided for by a plan of reorganization or readjustment, the payment of which is subordinated at least to the extent provided in this Article XV with respect to the
Debentures to the payment of all Senior Indebtedness, that may at the time be outstanding, provided that (i) such Senior Indebtedness is assumed by the new corporation, if any, resulting from any such reorganization or readjustment, and
(ii) the rights of the holders of such Senior Indebtedness are not, without the consent of such holders, altered by such reorganization or readjustment. The consolidation of the Company with, or the merger of the Company into, another
corporation or the liquidation or dissolution of the Company following the conveyance or transfer of its property as an entirety, or substantially as an entirety, to another corporation upon the terms and conditions provided for in Article XI of
this Indenture shall not be deemed a dissolution, winding-up, liquidation or reorganization for the purposes of this Section if such other corporation shall, as a part of such consolidation, merger, conveyance or transfer, comply with the conditions
stated in Article XI of this Indenture. Nothing in Section 15.2 or in this Section shall apply to claims of, or payments to, the Trustee under or pursuant to Section 6.6 of this Indenture.



53



---

Section 15.4. Subrogation. Subject to the payment in full of all Senior Indebtedness,
the Securityholders shall be subrogated to the rights of the holders of such Senior Indebtedness to receive payments or distributions of cash, property or securities of the Company, applicable to such Senior Indebtedness until the principal of (and
premium, if any) and interest on the Debentures shall be paid it full. For the purposes of such subrogation, no payments or distributions to the holders of such Senior Indebtedness of any cash, property or securities to which the Securityholders or
the Trustee would be entitled except for the provisions of this Article XV, and no payment over pursuant to the provisions of this Article XV to or for the benefit of the holders of such Senior Indebtedness by Securityholders or the Trustee, shall,
as between the Company, its creditors other than holders of Senior Indebtedness of the Company, and the holders of the Debentures be deemed to be a payment or distribution by the Company to or on account of such Senior Indebtedness. It is understood
that the provisions of this Article XV are intended solely for the purposes of defining the relative rights of the holders of the Securities, on the one hand, and the holders of such Senior Indebtedness, on the other hand.

Nothing contained in this Article XV or elsewhere in this Indenture or in the Debentures is intended to or shall impair, as between the Company, its
creditors other than the holders of Senior Indebtedness, and the holders of the Debentures, the obligation of the Company, which is absolute and unconditional, to pay to the holders of the Debentures the principal of (and premium, if any) and
interest on the Debentures as and when the same shall become due and payable in accordance with their terms, or is intended to or shall affect the relative rights of the holders of the Debentures and creditors of the Company, other than the holders
of Senior Indebtedness, nor shall anything herein or therein prevent the Trustee or the holder of any Debenture from exercising all remedies otherwise permitted by applicable law upon default under this Indenture, subject to the rights, if any,
under this Article XV of the holders of such Senior Indebtedness in respect of cash, property or securities of the Company, received upon the exercise of any such remedy.

Upon any payment or distribution of assets of the Company referred to in this Article XV, the Trustee, subject to the provisions of Article VI of this Indenture, and the Securityholders shall be entitled to
conclusively rely upon any order or decree made by any court of competent jurisdiction in which such dissolution, winding-up, liquidation or reorganization proceedings are pending, or a certificate of the receiver, trustee in bankruptcy, liquidation
trustee, agent or other Person making such payment or distribution, delivered to the Trustee or to the Securityholders, for the purposes of ascertaining the Persons entitled to participate in such distribution, the holders of Senior Indebtedness and
other indebtedness of the Company, the amount thereof or payable thereon, the amount or amounts paid or distributed thereon and all other facts pertinent thereto or to this Article XV.

Section 15.5. Trustee to Effectuate Subordination. Each Securityholder by such Securityholders acceptance thereof authorizes and
directs the Trustee on such Securityholders behalf to take such action as may be necessary or appropriate to effectuate the subordination provided in this Article XV and appoints the Trustee such Securityholders attorney-in-fact for any
and all such purposes.



54



---

Section 15.6. Notice by the Company. The Company shall give prompt written notice to a
Responsible Officer of the Trustee at the Principal Office of the Trustee of any fact known to the Company that would prohibit the making of any payment of monies to or by the Trustee in respect of the Debentures pursuant to the provisions of this
Article XV. Notwithstanding the provisions of this Article XV or any other provision of this Indenture, the Trustee shall not be charged with knowledge or the existence of any facts that would prohibit the making of any payment of monies to or by
the Trustee in respect of the Debentures pursuant to the provisions of this Article XV, unless and until a Responsible Officer of the Trustee at the Principal Office of the Trustee shall have received written notice thereof from the Company or a
holder or holders of Senior Indebtedness or from any trustee therefor; and before the receipt of any such written notice, the Trustee, subject to the provisions of Article VI of this Indenture, shall be entitled in all respects to assume that no
such facts exist; provided,however, that if the Trustee shall not have received the notice provided for in this Section at least 2 Business Days prior to the date upon which by the terms hereof any money may become payable for any
purpose (including, without limitation, the payment of the principal of (or premium, if any) or interest on any Debenture), then anything herein contained to the contrary notwithstanding, the Trustee shall have full power and authority to receive
such money and to apply the same to the purposes for which they were received, and shall not be affected by any notice to the contrary that may be received by it within 2 Business Days prior to such date.

The Trustee, subject to the provisions of Article VI of this Indenture, shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself to be a holder of Senior Indebtedness (or a trustee or representative on behalf of such holder), to establish that such notice has been given by a holder of such Senior Indebtedness or a trustee or representative on
behalf of any such holder or holders. In the event that the Trustee determines in good faith that further evidence is required with respect to the right of any Person as a holder of such Senior Indebtedness to participate in any payment or
distribution pursuant to this Article XV, the Trustee may request such Person to furnish evidence to the reasonable satisfaction of the Trustee as to the amount of such Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution, and any other facts pertinent to the rights of such Person under this Article XV, and, if such evidence is not furnished, the Trustee may defer any payment to such Person pending judicial
determination as to the right of such Person to receive such payment.

Section 15.7. Rights of the Trustee; Holders of Senior
Indebtedness. The Trustee in its individual capacity shall be entitled to all the rights set forth in this Article XV in respect of any Senior Indebtedness at any time held by it, to the same extent as any other holder of Senior
Indebtedness, and nothing in this Indenture shall deprive the Trustee of any of its rights as such holder.

With respect to the holders of
Senior Indebtedness, the Trustee undertakes to perform or to observe only such of its covenants and obligations as are specifically set forth in this Article XV, and no implied covenants or obligations with respect to the holders of such Senior
Indebtedness shall be read into this Indenture against the Trustee. The Trustee shall not be deemed to owe any fiduciary duty to the holders of such Senior Indebtedness and, subject to the provisions of Article VI of this Indenture, the Trustee
shall not be liable to any holder of such Senior Indebtedness if it shall pay over or deliver to Securityholders, the Company or any other Person money or assets to which any holder of such Senior Indebtedness shall be entitled by virtue of this
Article XV or otherwise.



55



---

Nothing in this Article XV shall apply to claims of, or payments to, the Trustee under or pursuant to
Section 6.6.

Section 15.8. Subordination May Not Be Impaired. No right of any present or future holder of any
Senior Indebtedness to enforce subordination as herein provided shall at any time in any way be prejudiced or impaired by any act or failure to act on the part of the Company, or by any act or failure to act, in good faith, by any such holder, or by
any noncompliance by the Company, with the terms, provisions and covenants of this Indenture, regardless of any knowledge thereof that any such holder may have or otherwise be charged with.

Without in any way limiting the generality of the foregoing paragraph, the holders of Senior Indebtedness may, at any time and from time to time, without
the consent of or notice to the Trustee or the Securityholders, without incurring responsibility to the Securityholders and without impairing or releasing the subordination provided in this Article XV or the obligations hereunder of the holders of
the Debentures to the holders of such Senior Indebtedness, do any one or more of the following: (i) change the manner, place or terms of payment or extend the time of payment of, or renew or alter, such Senior Indebtedness, or otherwise amend
or supplement in any manner such Senior Indebtedness or any instrument evidencing the same or any agreement under which such Senior Indebtedness is outstanding (ii) sell, exchange, release or otherwise deal with any property pledged, mortgaged
or otherwise securing such Senior Indebtedness; (iii) release any Person liable in any manner for the collection of such Senior Indebtedness; and (iv) exercise or refrain from exercising any rights against the Company, and any other
Person.

June 26, 2003

Columbia Trust Bancorp, a Washington corporation (the Company which term
includes any successor Person under the Indenture hereinafter referred to), for value received promises to pay to U.S. Bank National Association, not in its individual capacity but solely as Institutional Trustee for Columbia Trust Statutory Trust I
(the Holder) or registered assigns, the principal sum of three million ninety-three thousand dollars ($3,093,000.00) on June 26,



A-1-2



---

2033, and to pay interest on said principal sum from June 26, 2003, or from the most recent interest payment date (each such date, an Interest
Payment Date) to which interest has been paid or duly provided for, quarterly (subject to deferral as set forth herein) in arrears on March 26, June 26, September 26 and December 26 of each year commencing on
September 26, 2003, at an annual rate equal to 4.16% beginning on (and including) the date of original issuance and ending on (but excluding) September 26, 2003 and at an annual rate for each successive period beginning on (and including)
September 26, 2003, and each succeeding Interest Payment Date, and ending on (but excluding) the next succeeding Interest Payment Date (each a Distribution Period), equal to 3-Month LIBOR, determined as described below, plus 3.10%
(the Coupon Rate); provided,however, that prior to June 26, 2008, the Coupon Rate shall not exceed 11.75%, applied to the principal amount hereof, until the principal hereof is paid or duly provided for or made
available for payment, and on any overdue principal and (without duplication and to the extent that payment of such interest is enforceable under applicable law) on any overdue installment of interest (including Additional Interest) at the Interest
Rate in effect for each applicable period, compounded quarterly, from the dates such amounts are due until they are paid or made available for payment. The amount of interest payable for any period will be computed on the basis of the actual number
of days in the Distribution Period concerned divide by 360. In the event that any date on which interest is payable on this Debenture is not a Business Day, then a payment of the interest payable on such date will be made on the next succeeding day
which is a Business Day (and without any interest or other payment in respect of any such delay), except that, if such Business Day is in the next succeeding calendar year, such payment shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on the date the payment was originally payable. The interest installment so payable, and punctually paid or duly provided for, on any Interest Payment Date will, as provided in the Indenture, be
paid to the Person in whose name this Debenture (or one or more Predecessor Securities) is registered at the close of business on the regular record date for such interest installment, which shall be fifteen days prior to the day on which the
relevant Interest Payment Date occurs. Any such interest installment not so punctually paid or duly provided for shall forthwith cease to be payable to the Holder on such regular record date and may be paid to the Person in whose name this Debenture
(or one or more Predecessor Securities) is registered at the close of business on a special record date.

3-Month LIBOR as used
herein, means the London interbank offered interest rate for three-month U.S. dollar deposits determined by the Trustee in the following order of priority: (i) the rate expressed as a percentage per annum) for U.S. dollar deposits having a
three-month maturity that appears on Telerate Page 3750 as of 11:00 a.m. (London time) on the related Determination Date (Telerate Page 3750 means the display designated as Page 3750 on the Dow Jones Telerate Service or such
other page as may replace Page 3750 on that service or such other service or services as may be nominated by the British Bankers Association as the information vendor for the purpose of displaying London interbank offered rates for U.S. dollar
deposits); (ii) if such rate cannot be identified on the related Determination Date, the Trustee will request the principal London offices of four leading banks in the London interbank market to provide such banks offered quotations
(expressed as percentages per annum) to prime banks in the London interbank market for U.S. dollar deposits having a three-month maturity as of 11:00 a.m. (London time) on such Determination Date. If at least two quotations are provided, 3-Month
LIBOR will be the arithmetic mean of such quotations; (iii) if fewer than two such quotations are provided as requested in clause (ii) above, the Trustee will request four major New York City



A-1-3



---

banks to provide such banks offered quotations (expressed as percentages per annum) to leading European banks for loans in U.S. dollars as of 11:00
a.m. (London time) on such Determination Date. If at least two such quotations are provided, 3-Month LIBOR will be the arithmetic mean of such quotations; and (iv) if fewer than two such quotations are provided as requested in clause
(iii) above, 3-Month LIBOR will be a 3-Month LIBOR determined with respect to the Distribution Period immediately preceding such current Distribution Period. If the rate for U.S. dollar deposits having a three-month maturity that initially
appears on Telerate Page 3750 as of 11:00 a.m. (London time) on the related Determination Date is superseded on the Telerate Page 3750 by a corrected rate by 12:00 noon (London time) on such Determination Date, then the corrected rate as so
substituted on the applicable page will be the applicable 3-Month LIBOR for such Determination Date. As used herein, Determination Date means the date that is two London Banking Days (i.e., a business day in which dealings in deposits in
U.S. dollars are transacted in the London interbank market) preceding the commencement of the relevant Distribution Period.

The Interest
Rate for any Distribution Period will at no time be higher than the maximum rate then permitted by New York law as the same may be modified by United States law.

All percentages resulting from any calculations on the Debentures will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded
upward (e.g., 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655), and all dollar amounts used in or resulting from such calculation will be rounded to the nearest cent (with one-half cent being rounded upward)).

The principal of and interest on this Debenture shall be payable at the office or agency of the Trustee (or other paying agent appointed by the Company)
maintained for that purpose in any coin or currency of the United States of America that at the time of payment is legal tender for payment of public and private debts; provided, however, that payment of interest may be made by check
mailed to the registered holder at such address as shall appear in the Debenture Register if a request for a wire transfer by such holder has not been received by the Company or by wire transfer to an account appropriately designated by the holder
hereof. Notwithstanding the foregoing, so long as the holder of this Debenture it the Institutional Trustee, the payment of the principal of and interest on this Debenture will be made it immediately available funds at such place and to such account
as may be designated by the Trustee.

So long as no Event of Default has occurred and is continuing, the Company shall have the right from
time to time, and without causing an Event of Default, to defer payments of interest on the Debentures by extending the interest payment period on the Debentures at any time and from time to time during the term of the Debentures, for up to 20
consecutive quarterly periods (each such extended interest payment period, an Extension Period), during which Extension Period no interest (including Additional Interest) shall be due and payable (except any Additional Sums that may be
due and payable). No Extension Period may end on a date other than an Interest Payment Date. During an Extension Period interest will continue to accrue on the Debentures, and interest on such accrued interest will accrue at an annual rate equal to
the Interest Rate in effect for such Extension Period, compounded quarterly from the date such interest would have been payable were it not for the Extension Period, to the extent permitted by law (such interest referred to herein as
Additional Interest). At the end of any such Extension



A-1-4



---

Period the Company shall pay all interest then accrued and unpaid on the Debentures (together, with Additional Interest thereon); provided,
however, that no Extension Period may extend beyond the Maturity Date; provided further, however, that during any such Extension Period, the Company shall not and shall not permit any Affiliate to engage in any of the
activities or transactions described on the reverse side hereof and in the Indenture. Prior to the termination of any Extension Period, the Company may further extend such period, provided that such period together with all such previous and further
consecutive extensions thereof shall not exceed 20 consecutive quarterly periods, or extend beyond the Maturity Date. Upon the termination of any Extension Period and upon the payment of all accrued and unpaid interest and Additional
Interest, the Company may commence a new Extension Period, subject to the foregoing requirements. No interest or Additional Interest shall be due and payable during an Extension Period, except at the end thereof, but each installment of
interest that would otherwise have been due and payable during such Extension Period shall bear Additional Interest. The Company must give the Trustee notice of its election to begin or extend an Extension Period at least 5 Business Days prior to
the regular record date (as such term is used in Section 2.8 of the Indenture) immediately preceding the Interest Payment Date with respect to which interest on the Debentures would have been payable except for the election to begin or extend
such Extension Period.

The indebtedness evidenced by this Debenture is, to the extent provided in the Indenture, subordinate and junior in
right of payment to the prior payment in full of all Senior Indebtedness, and this Debenture is issued subject to the provisions of the Indenture with respect thereto. Each holder of this Debenture, by accepting the same, (a) agrees to and
shall be bound by such provisions, (b) authorizes and directs the Trustee on his or her behalf to take such action as may be necessary or appropriate to acknowledge or effectuate the subordination so provided and (c) appoints the Trustee
his or her attorney-in-fact for any and all such purposes. Each holder hereof, by his or her acceptance hereof, hereby waives all notice of the acceptance of the subordination provisions contained herein and in the Indenture by each holder of Senior
Indebtedness, whether now outstanding or hereafter incurred, and waives reliance by each such holder upon said provisions.

This Debenture
shall not be entitled to any benefit under the Indenture hereinafter referred to, be valid or become obligatory for any purpose until the certificate of authentication hereon shall have been signed by or on behalf of the Trustee.

The provisions of this Debenture are continued on the reverse side hereof and such provisions shall for all purposes have the same effect as though fully
set forth at this place.

[FORM OF REVERSE OF DEBENTURE]

This Debenture is one of the floating rate junior subordinated deferrable interest debentures of the Company, all issued or to be issued under and
pursuant to the Indenture dated as of June 26, 2003 (the Indenture), duly executed and delivered between the Company and the Trustee, to which Indenture reference is hereby made for a description of the rights, limitations of
rights, obligations, duties and immunities thereunder of the Trustee, the Company and the holders of the Debentures. The Debentures are limited in aggregate principal amount as specified in the Indenture.

Upon the occurrence and continuation of a Special Event prior to June 26, 2008, the Company shall have the right to redeem the Debentures in whole,
but not in part, at any Interest Payment Date, within 120 days following the occurrence of such Special Event, at the Special Redemption Price.

In addition, the Company shall have the right to redeem the Debentures, in whole or in part, but in all cases in a principal amount with integral multiples of $1,000.00, on any Interest Payment Date on or after June 26, 2008, at the
Redemption Price.

Prior to 10:00 a.m. New York City time on the Redemption Date or Special Redemption Date, as applicable, the Company
will deposit with the Trustee or with one or more paying agents an amount of money sufficient to redeem on the Redemption Date or the Special Redemption Date, as applicable, all the Debentures so called for redemption at the appropriate Redemption
Price or Special Redemption Price.

If all, or less than all, the Debentures are to be redeemed, the Company will give the Trustee notice
not less than 45 nor more than 60 days, respectively, prior to the Redemption Date or Special Redemption Date, as applicable, as to the aggregate principal amount of Debentures to be redeemed and the Trustee shall select, in such manner as in its
sole discretion it shall deem appropriate and fair, the Debentures or portions thereof (in integral multiples of $1,000.00) to be redeemed.

Notwithstanding the foregoing, any redemption of Debentures by the Company shall be subject to the receipt of any and all required regulatory approvals.

In case an Event of Default shall have occurred and be continuing, upon demand of the Trustee, the principal of all of the Debentures shall become due and payable in the manner, with the effect and subject to the
conditions provided in the Indenture.

The Indenture contains provisions permitting the Company and the Trustee, with the consent of the
holders of not less than a majority in aggregate principal amount of the Debentures at the time outstanding, to execute supplemental indentures for the purpose of adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of any supplemental indenture or of modifying in any manner the rights of the holders of the Debentures; provided, however, that no such supplemental indenture shall without the consent of the holders of
each Debenture then outstanding and affected thereby (i) change the fixed maturity of any Debenture, or reduce the principal amount thereof or any premium thereon, or reduce the rate or extend the time of payment of interest thereon, or reduce
any amount

payable on redemption thereof or make the principal thereof or any interest or premium thereon payable in any coin or currency other than that provided in
the Debentures, or impair or affect the right of any Securityholder to institute suit for payment thereof or impair the right of repayment, if any, at the option of the holder, or (ii) reduce the aforesaid percentage of Debentures the holders
of which are required to consent to any such supplemental indenture.

The Indenture also contains provisions permitting the holders of a
majority in aggregate principal amount of the Debentures at the time outstanding on behalf of the holders of all of the Debentures to waive (or modify any previously granted waiver of) any past default or Event of Default, and its consequences,
except a default (a) in the payment of principal of, premium, if any, or interest on any of the Debentures, (b) in respect of covenants or provisions hereof or of the Indenture which cannot be modified or amended without the consent of the
holder of each Debenture affected, or (c) in respect of the covenants contained in Section 3.9 of the Indenture; provided, however, that if the Debentures are held by the Trust or a trustee of such trust, such waiver or
modification to such waiver shall not be effective until the holders of a majority in Liquidation Amount of Trust Securities of the Trust shall have consented to such waiver or modification to such waiver, provided, further, that if
the consent of the holder of each outstanding Debenture is required, such waiver shall not be effective until each holder of the Trust Securities of the Trust shall have consented to such waiver. Upon any such waiver, the default covered thereby
shall be deemed to be cured for all purposes of the Indenture and the Company, the Trustee and the holders of the Debentures shall be restored to their former positions and rights hereunder, respectively; but no such waiver shall extend to any
subsequent or other default or Event of Default or impair any right consequent thereon. Whenever any default or Event of Default hereunder shall have been waived as permitted by the Indenture, said default or Event of Default shall for all purposes
of the Debentures and the Indenture be deemed to have been cured and to be not continuing.

No reference herein to the Indenture and no
provision of this Debenture or of the Indenture shall alter or impair the obligation of the Company, which is absolute and unconditional, to pay the principal of and premium, if any, and interest, including Additional Interest, on this Debenture at
the time and place and at the rate and in the money herein prescribed.

The Company has agreed that if Debentures are initially issued to
the Trust or a trustee of such Trust in connection with the issuance of Trust Securities by the Trust (regardless of whether Debentures continue to be held by such Trust) and (i) there shall have occurred and be continuing an Event of Default,
(ii) the Company shall be in default with respect to its payment of any obligations under the Capital Securities Guarantee, or (iii) the Company shall have given notice of its election to defer payments of interest on the Debentures by
extending the interest payment period as provided herein and such Extension Period, or any extension thereof, shall be continuing, then the Company shall not, and shall not allow any Affiliate of the Company to, (x) declare or pay any dividends
or distributions on, or redeem, purchase, acquire, or make a liquidation payment with respect to, any of the Companys capital stock or its Affiliates capital stock (other than payments of dividends or distributions to the Company) or
make any guarantee payments with respect to the foregoing or (y) make any payment of principal of or interest or premium, if any, on or repay, repurchase or redeem any debt securities of the Company or any Affiliate that rank pari passu
in all respects with or junior in interest to the Debentures (other

than, with respect to clauses (x) and (y) above, (1) repurchases, redemptions or other acquisitions of shares of capital stock of the Company
in connection with any employment contract, benefit plan or other similar arrangement with or for the benefit of one or more employees, officers, directors or consultants, in connection with a dividend reinvestment or stockholder stock purchase plan
or in connection with the issuance of capital stock of the Company (or securities convertible into or exercisable for such capital stock) as consideration in an acquisition transaction entered into prior to the applicable Extension Period, if any,
(2) as a result of any exchange or conversion of any class or series of the Companys capital stock (or any capital stock of a subsidiary of the Company) for any class or series of the Companys capital stock or of any class or series
of the Companys indebtedness for any class or series of the Companys capital stock, (3) the purchase of fractional interests in shares of the Companys capital stock pursuant to the conversion or exchange provisions of such
capital stock or the security being converted or exchanged, (4) any declaration of a dividend in connection with any stockholders rights plan, or the issuance of rights, stock or other property under any stockholders rights plan, or
the redemption or repurchase of rights pursuant thereto, (5) any dividend in the form of stock, warrants, options or other rights where the dividend stock or the stock issuable upon exercise of such warrants, options or other rights is the same
stock as that on which the dividend is being paid or ranks pari passu with or junior to such stock and any cash payments in lieu of fractional shares issued in connection therewith, or (6) payments under the Capital Securities
Guarantee).

The Debentures are issuable only in registered, certificated form without coupons and in minimum denominations of $100,000.00
and any multiple of $1,000.00 in excess thereof. As provided in the Indenture and subject to the transfer restrictions and limitations as may be contained herein and therein from time to time, this Debenture is transferable by the holder hereof on
the Debenture Register of the Company. Upon due presentment for registration of transfer of any Debenture at the Principal Office of the Trustee or at any office or agency of the Company maintained for such purpose as provided in Section 3.2 of
the Indenture, the Company shall execute, the Company or the Trustee shall register and the Trustee or the Authenticating Agent shall authenticate and make available for delivery in the name of the transferee or transferees a new Debenture for a
like aggregate principal amount. All Debentures presented for registration of transfer or for exchange or payment shall (if so required by the Company or the Trustee or the Authenticating Agent) be duly endorsed by, or be accompanied by a written
instrument or instruments of transfer in form satisfactory to, the Company and the Trustee or the Authenticating Agent duly executed by the holder or his attorney duly authorized in writing. No service charge shall be made for any exchange or
registration of transfer of Debentures, but the Company or the Trustee may require payment of a sum sufficient to cover any tax, fee or other governmental charge that may be imposed in connection therewith.

Prior to due presentment for registration of transfer of any Debenture, the Company, the Trustee, any Authenticating Agent, any paying agent, any
transfer agent and any Debenture registrar may deem the Person in whose name such Debenture shall be registered upon the Debenture Register to be, and may treat him as, the absolute owner of such Debenture (whether or not such Debenture shall be
overdue) for the purpose of receiving payment of or on account of the principal of, premium, if any, and interest on such Debenture and for all other purposes; and neither the Company nor the Trustee nor any Authenticating Agent nor any paying agent
nor any transfer agent nor any Debenture registrar shall be affected by any notice to the contrary. All such payments so made to any holder for the time being or upon his order shall be valid, and, to the extent of the sum or sums so paid, effectual
to satisfy and discharge the liability for moneys payable upon any such Debenture.
